The Infineon BGT24MTR11 is a silicon germanium MMIC for signal generation and reception, operating from 24.00 to 26.00GHz. It is based on a 24GHz fundamental voltage controlled oscillator. Switchable frequency prescalers are included with output frequencies of 1.5GHz and 23kHz. The main RF output delivers upto 8dBm signal power to feed an antenna and an auxiliary LO output is available to provide LO signal to separate receiver components. An LO buffer amplifier is included to relax LO drive requirements and a LNA provides low noise figure. A RC polyphase filter (PPF) is used for LO quadrature phase generation of the homodyne quadrature downconversion mixer. Output power sensors as well as a temperature sensor are implemented for monitoring purposes. The device is controlled via SPI and is manufactured in a 0.18μm SiGe:C technology offering a cutoff frequency of 200GHz.
