Ka-Band Low Noise Amplifier Module LNA11202131SS

The LNA11202131SS is a multi-stage modular low noise amplifier covering the full Ka-band from 21-31 GHz, delivering 34 dB of gain with a noise figure of just 2.5 dB. Designed for integration into satellite payloads, ground station receive chains, and test systems, it provides the low-noise amplification required for weak Ka-band signal reception with high sensitivity.

The module operates from a wide single-supply voltage range of 7-40 V, making it compatible with a broad range of power system architectures. It incorporates an enable/disable function for power management, plus current and temperature sensor outputs for remote health monitoring and fault analysis – capabilities essential for both satellite payload integration and unmanned ground terminal applications.

The LNA11202131SS is fully enclosed in a robust housing with 2.92 mm RF connectors and a D-Sub connector for DC power, enable signal, current, and temperature sensor connections. Its wideband 21-31 GHz coverage encompasses both the Ka-band downlink adjacent bands and the full Ka-band uplink satellite frequency allocations, enabling use in both satellite receive payloads and ground terminal uplink sensing/monitoring applications.
