The \u003cstrong\u003eSSB LNA-ISM-433\u003c\/strong\u003e is a selective low noise pre-amplifier specifically \u003cstrong\u003edeveloped for reception between 433 and 435 MHz\u003c\/strong\u003e. With a \u003cstrong\u003etypical gain of 20 dB and a low noise figure of only 0.7 dB at 20 °C\u003c\/strong\u003e, this receive pre-amplifier is designed for applications where good signal amplification and the lowest possible noise addition are important.\u003c\/p\u003e\n\u003cp\u003eBut this LNA does more than just amplify. A \u003cstrong\u003ehigh-quality bandpass filter\u003c\/strong\u003e at the output helps suppress signals outside the desired frequency range. This not only amplifies the desired signal but also reduces the burden on the downstream receiver from unwanted signals outside the used band.\u003c\/p\u003e\n\u003cp\u003eThat makes the SSB LNA-ISM-433 an interesting technical solution for various analog and digital communication applications within the 433 MHz ISM band.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is a low noise pre-amplifier?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA low noise pre-amplifier, often abbreviated to LNA, is a low-noise pre-amplifier that amplifies a received RF signal before it is further processed by the receiver.\u003c\/p\u003e\n\u003cp\u003eFor weak signals, not only the amount of amplification is important. The amplifier itself should add as little additional noise to the signal as possible. Therefore, the noise figure is an important specification of an LNA.\u003c\/p\u003e\n\u003cp\u003eThe SSB LNA-ISM-433 has a specified noise figure of 0.7 dB at 20 °C and a typical gain of 20 dB. This makes this pre-amplifier specifically aimed at high-quality reception within its frequency range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifically for the 433 MHz ISM band\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis SSB pre-amplifier is not a general broadband amplifier. It is developed for the frequency range of 433 to 435 MHz.\u003c\/p\u003e\n\u003cp\u003eThis is an important advantage when signals within this frequency range are precisely what is interesting. At the output of the amplifier, there is a bandpass filter with high-quality components. This provides extra band selectivity and helps suppress strong, unwanted signals outside the usable band.\u003c\/p\u003e\n\u003cp\u003eAs a result, fewer unwanted signals reach the downstream receiver. The LNA-ISM-433 thus combines low-noise signal amplification with selective filtering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGaAs MMIC technology and high-quality RF construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSSB has used a GaAs MMIC on a high-quality microwave substrate board with SMD technology for the amplifier.\u003c\/p\u003e\n\u003cp\u003eThe input circuit is also explicitly focused on good noise characteristics. According to the manufacturer, high-quality components in a cell-design construction are used for this.\u003c\/p\u003e\n\u003cp\u003eThe input and output networks are designed for an impedance of 50 ohms with very small imaginary components. Together with a specified OIP3 of 32 dBm and IIP3 of 12 dBm, the amplifier is designed for both low noise and good large-signal behavior.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower supply locally or via the coaxial cable\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe SSB LNA-ISM-433 can be supplied with power in different ways.\u003c\/p\u003e\n\u003cp\u003eYou can connect a local power supply to the +12V DC connection. The allowed operating voltage is between 8 and 14V, and the specified current consumption is 110 mA.\u003c\/p\u003e\n\u003cp\u003eAnother option is power supply via the coaxial output cable using a suitable remote feeder, such as the SSB DCC 5000pro, which is placed before the receiver input.\u003c\/p\u003e\n\u003cp\u003eWhen a suitable receiver itself provides the power supply for an LNA via the antenna connection, the coaxial output of the pre-amplifier can be connected directly to the antenna input of the receiver according to the instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUse a good coaxial cable\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWith weak signals, you want to prevent some of the benefits of a low-noise pre-amplifier from being lost in the antenna cable. The manufacturer therefore advises using the shortest possible coaxial cable with low losses on the antenna side.\u003c\/p\u003e\n\u003cp\u003eExamples given are Ecoflex 15, Aircom Premium, and Ecoflex 10. For the output cable, a thinner coaxial cable such as Aircell 7 can optionally be used, according to the instructions.\u003c\/p\u003e\n\u003cp\u003eSSB also advises taking transforming cable lengths into account when determining the cable length. For this, the manufacturer provides the formula Lambda \/ 2 × N × V, where Lambda is the wavelength, N is a natural number, and V is the velocity factor of the coaxial cable used.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant: for reception only\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAn important point to note about the SSB LNA-ISM-433 is that this pre-amplifier does not have automatic transmit\/receive switching.\u003c\/p\u003e\n\u003cp\u003eThe LNA is intended as a receive pre-amplifier. Too high a signal level at the input or output can damage the device.\u003c\/p\u003e\n\u003cp\u003eTherefore, do not simply use the amplifier in a signal path where a transmit signal may also be present. Carefully check how your complete antenna and receive configuration is set up and what signal levels may occur before installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eFor 433 MHz ISM: selective receive pre-amplifier for 433 to 435 MHz.\u003cbr\u003e\n\n\u003c\/li\u003e\n\n\u003cli\u003eLow noise pre-amplifier: noise figure of 0.7 dB at 20 °C and typical gain of 20 dB.\u003cbr\u003e\n\n\u003c\/li\u003e\n\n\u003cli\u003eSelective filtering: bandpass filter helps suppress unwanted signals outside the usable band.\u003cbr\u003e\n\n\u003c\/li\u003e\n\n\u003cli\u003eHigh-quality RF technology: built around GaAs MMIC technology with a 50 ohm input and output.\u003cbr\u003e\n\n\u003c\/li\u003e\n\n\u003cli\u003eFlexible power supply: locally via the DC connection or, with a suitable installation, via the coaxial output line.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFor serious 433 MHz reception\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen working with weak signals, every component between the antenna and the receiver counts. A good low noise pre-amplifier should therefore not simply amplify as much as possible. Low inherent noise, selectivity, and good behavior with strong signals are at least as important.\u003c\/p\u003e\n\u003cp\u003ePrecisely that is what the SSB LNA-ISM-433 is aimed at. The combination of 20 dB typical gain, a noise figure of 0.7 dB, and filtering outside the desired band makes this LNA a specialized solution for high-quality reception between 433 and 435 MHz.\u003c\/p\u003e\n\u003cp\u003eDo you want to get more out of a suitable receive installation for the 433 MHz ISM band?
