Signal Technology released a transceiver for 38 GHz Ultra High Capacity point-to-point and point-to-multipoint radio applications. This is a highly integrated TR assembly designed for next generation radio platforms utilizing 4 to 256 QAM modulation and passing data rates through 622 Mb/s. On the transmit side, the design provides for millimeter-wave upconversion and power amplification, including power attenuation and detection over a 45 dB dynamic range (35 dB closed loop). The receiver functionality includes millimeter-wave downconversion to 1st IF with receive signal level detection. An onboard EPROM is used to store all Rx/Tx calibration data over temperature and frequency. A diagnostic loopback function is also provided within the module. Both ETSI and FCC models are available.
