1. Principle

Double Channel Reception Front-end Principle

As above picture, the module consists of two same channels. The RF signal of 6 GHz ~18GHz will enter the SDLVA via amplifier, switch, digital attenuator and filter, which transform the large dynamic power signal into linear video frequency signal output.

2. In/Out Connector

2.1 RF Input Connector: HJG plug (X1, X2)
2.2 Video Frequency Output, Power Supply and Control Connector: DC-37P (X3)

3. Technical Specification

3.1 Input Signal Frequency Range: 6GHz ~ 18GHz
3.2 Input Signal Power Range: -50dBm~-5dBm (The attenuation is 20dB when the power is more than -10dBm , External Control)
