SRK1101 1-transmitter and 1-receiver 24GHz transceiver MMIC

GENERAL DESCRIPTION The SRK1101 is a fully integrated transceiver MMIC based on the state-of-art silicon germanium process. It operates in the 24 GHz ISM band from 24.00 to 24.25 GHz. It has 1 transmitting path that delivers 3 dBm to the antenna feed and 1 receiving path that provides a 25 dB voltage gain and a 11 dB noise figure. A frequency divider is included to generate signals with output frequencies of 1.5 GHz or 3 MHz. On-chip baluns are included to provide single-ended RF interfaces. The package is a compact 16-lead, 2.4 mm x 2.4 mm QFN.
