Description
The project objectives were to develope subelements for future highly integrated microwave equipment. An EM of a Ka-band LNA unit for Telecom payloads were also developed and tested.
Four LNA MMIC were developed and tested:
1. 30 GHz LNA MMIC
2. 18 GHz LNA MMIC
3. 14 GHz LNA MMIC
4. 6 GHz LNA MMIC
The LNA MMICs were designed using the OMMIC D01MH process which is a very low noise process.
Complete LNA chain BBs were developed to validate the MMIC performance in a typical package. The RF chain included a VGA for temperature compensation as well as an output amplifier with naked die transistors.
Two linear output amplifiers were also developed and tested:
1. 12 GHz PA MMIC
2. 4 GHz PA MMIC
The PA MMICs were designed using the UMS PPH25x process for high linearity. An LTCC package was developed to house the developed PA MMIC together with a driver MMIC.
Finally a Ka band LNA EM unit was designed manufactured and tested. The EM unit included secondary voltage regulators, temperature compensation circuits and a hermetic package with the LNA RF chain.
