Multi-Channel Wide Band Amplifier (MCA)

Multi-Channel Wide Band Amplifier (MCA)


The Dual Channel High Power Amplifier is a small, lightweight amplifier fully capable of extending the communication range for legacy and next generation waveforms.  The combination of two internal frequency channels (UHF, VHF/L-Band) provide for User Definable simultaneous 2 channel operation. The compact design is an ideal choice for airborne applications and compliant to MIL STD 704E.
