| Gallium Arsenide Microwave Amplifier. This is one of the micro-circuits inside a Celeritek CTR-990126 CPW microwave transceiver seen up close (see previous sample for an overall view). At microwave frequencies the shape of everything matters, and signals a nearly as happy to travel through air as they are through wire. Notice how in some places the signal path clearly continues across gaps where there is no wire: Interwoven loops of wire act like transmitting and receiving antennas, or if you will like capacitors, that are able to pass only very high-frequency signals. I'm not an expert in microwave circuitry so I can't tell you exactly what each of these components is, but somewhere in there are gallium arsenide transistors and diodes.
