BGT24MTR11 Datasheet – 24 GHz Transceiver MMIC – Infineon
Silicon Germanium 24 GHz Transceiver MMIC
BGT24MTR11 overview
The BGT24MTR11 is a Silicon Germanium 24 GHz Transceiver MMIC made by Infineon Technologies AG, supplied in a VQFN32-9 Type package. The absolute maximum ratings table on this page lists the 20 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the BGT24MTR11 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
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.
