400-403-406MHz Low Noise Preamplifier NF 0.6dB

This 400-403-406MHz Low Noise Preamplifier consists of a super low-loss input band-pass filter with a low noise preamplifier. Intended for Long-range communication, meteorological satellites (Data Collection Systems), Earth exploration-satellite services (EESS) in the frequency range 400MHz – 403MHz – 406MHz.  An integrated 403MHz Bandpass filter is perfect for suppressing all out-of-band signals from HF, 6m, 4m, 2m, or 23cm stations. This preamplifier is very immune to out-of-band signals.

 

400-403-406MHz Low Noise Preamplifier Appearance:

Measured results of 400-403-406MHz Low Noise Preamplifier:

HF < -49dB
50 MHz -37dB
70 MHz -29dB
144MHz -10 dB
400-403-406MHz + 20.5dB NF = 0.6 dB Input RL better than -15dB, IP3out >37dBm
806MHz -8dB
1296.1MHz -36dB
Power consumption: +10-15V / 100mA

These excellent results were achieved by careful selection of components and design. Thanks to input filtering, the preamplifier and bandpass filter combination are significantly less susceptible to interference from strong out-of-band signals. Compared to output filtering.
