bgt24mtr11硅锗24 GHz收发器集成电路

　　The BGT24MTR11 is a Silicon Germanium MMIC for signal generation and reception， operating from 24.0 up to 26.0 GHz. It is based on a 24 GHz fundamental voltage controlled oscillator. Switchable frequency prescalers are included with output frequencies of 1.5 GHz and 23 kHz. The main RF output delivers typ. 11dBm signal power to feed an antenna and an auxiliary LO output is available to provide LO signal to separate receiver components. A LNA provides low noise figure and 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 200 GHz. The MMIC is packaged in a 32 pin leadless RoHs compliant VQFN package.
