Q-band LNA Q-BAND WIDEBAND LNA FOR GROUND SEGMENT

Objectives

The objective of the activity is the design, manufacture, and test of a prototype of a commercially viable 40-GHz LNA for gateway application. The LNA is based on European monolithic microwave integrated circuit (MMIC) technology.

Challenges

In this project low Noise Figure, high gain and very good matching are demanded over a significant fraction of the Q-band. LNAFIN Oy leverages its MMIC and waveguide know-how to meet these challenges with an internally redundant WR-22 packaged LNA unit.

Benefits

This product is the first WR-22 packaged LNA to enter the marketplace which has high gain, NF at ca. 2.5 dB with simultaneous input and output port RL values exceeding 18 dB from 35 to 45 GHz.

Features

The designed LNA unit is WR-22 packaged so that it has two separate LNAs internally. These LNAs can be switched on/off externally so as to increase product reliability in gateway use. The required telecommand interface is established using the same single connector, which is utilised for LNA biasing.

System architecture

This is a WR-22 waveguide packaged ultra low-noise LNA. The unit has internal redundancy as it includes two high-performance LNA units in parellel. The units can be turned on/off by an external telecommand interface.

Plan

Project has two (2) Phases which include five (5) Tasks.

Current status

Project has entered Phase 2.
