BGT24MTR12 24 – 24.25 GHz | 210 mA @ 3.3 V supply | 26 dB gain | 12 dB noise figure (NFSSB)
24GHz silicon germanium MMIC for signal generation and reception
The BGT24MTR12 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. A switchable frequency prescaler is included with output frequencies of 1.5GHz and 23kHz. The main RF output delivers up to 8 dBm signal power to feed an antenna. 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. The MMIC is packaged in a 32 pin leadless RoHs compliant VQFN package.
