1. Input Downlink Diplexer – has low bandpass insertion loss and high selectivity for two distinct
Downlink frequency bands.
2. Downlink Pre-amp’s – are low noise amplifiers that drive the Downlink PA’s and offer 25dB
Gain.
3. Downlink PA’s – are power amplifiers with an ALC circuit which offer 30dB Gain.
4. Output Downlink Diplexer - has low bandpass insertion loss and high selectivity for two
distinct Downlink frequency bands.
5. Uplink/Downlink Combiner – is Diplexed configured and has low bandpass insertion loss and
high selectivity for the Uplink and Downlink frequency bands.
6. Input Uplink Diplexer – has low bandpass insertion loss and high selectivity for two distinct
Uplink frequency bands.
7. Uplink Pre-amp’s – are low noise amplifiers that drive the Uplink LPA”s and offer 25dB Gain.
8. Uplink LPA’s – are low power amplifier’s with an ALC circuit which offer 30dB Gain.
9. Output Uplink Diplexer - has low bandpass insertion loss and high selectivity for two distinct
Uplink frequency bands.
