A K-band single-chip transmitter

摘要

A very small K-band transmitter chip has been designedand fabricated for the first time. The transmitter chip contains a localoscillator, a balanced FET upconverter, and amplifiers. It converts1-GHz IF signals up to 25 GHZ with a conversion gain of 10 dB andgenerates a maximum power of 10 dBm. Lumped-constant meander, spiralinductors, and high-impedance coplanar waveguides are used to reducesize. The chip is only 3.3 mm×1.3 mm due to effective uniplanarMMIC (monolithic microwave IC) design techniques and a simple localoscillator configuration
