Type 7-551 Series Dual Frequency GPS Antenna Electronic Unit

The 7-551 Series of Antenna Electronic Units (AEU) (5V) are dual frequency GPS (Global Positioning Satellite System) pre-amplifiers designed to meet both electrical and environmental military aircraft application requirements. The pre-amplifier amplifies signals in the two GPS bands (L1 and L2) while rejecting spurious signals outside ±60 MHz of centre-bands (60 dB filtering incorporated). The pre-amplifier also incorporates a limiter circuit for high power protection. The pre-amplifiers are supplied configured to provide factory set antenna electronics gains that range from 4 dB to 24 dB. The 7-551 is powered from 5 V dc supplied on the RF output connector.

  • M-Code Compatible
