RF Amplifier Module - for OCMR
 

About the Product

The RF Amplifier Module (AGC3) fits into the OCM chassis with plug-and-play technology to suit a variety of applications.

The AGC3-1000-1 accepts forward path RF signals from 45 MHz to 1000 MHz via the RF input. The module provides adjustable gain from 5 dB to 25 dB, with a single output port.

The AGC3-200 accepts return path RF signal from 5 MHz to 200 MHz via the RF input. The module provides adjustable gain from 5 dB to 25 dB with a single output port.

Electronic gain and slope controls allow the module to be customised for many situations.

The forward path version provides broadband AGC to maintain a constant RF output level for up to 20 dB of variation in input level. The return path version has 4.5 MHz pilot based AGC, which can be disabled for MGC applications.

Microprocessor based status monitoring and control is available, which is operable from either the local OCM keypad or remotely via a network, using the PBN NMS3 network management software. All module settings are retained in non-volatile memory to ensure trouble-free operation.
