The Diamond DMAX50 is a high-quality, wideband preamplifier specifically designed for scanners and SDR receivers . With an impressive frequency range of 0.5 to 1500 MHz and adjustable gain from -20 dB to +20 dB , this amplifier offers maximum flexibility for capturing weak signals or attenuating strong ones.
Unique to the DMAX50 is its very low noise factor of just 3.5 dB , ensuring crystal-clear signal reception without distortion. This makes it the ideal choice for users who want to get the most out of their receiving equipment – from airband to UHF, from public service to commercial frequencies.
Applications:
- For radio scanner users who want to amplify weak signals
- SDR (Software Defined Radio) receivers with variable signal strength
- Professional monitoring work or as part of a measurement setup
- Ideal for situations without built-in ATT function (sensitivity reduction)
Benefits of the DMAX50:
- Wide frequency range: 0.5 – 1500 MHz
- Adjustable gain from -20 dB to +20 dB – amplifies or attenuates signals
- Low noise factor (NF 3.5 dB) for clean signal reproduction
- Strong components with high IP3 (+15 dBm) – resistant to strong signals
- Easy installation between antenna and receiver
- Power supply via 13.8V DC, can also be used with 12V cigarette lighter plug (included)
Installation instructions:
Installation is simple, see also the images above at the end of the product photos.
