Description
The BGT24LTR11 is a Silicon Germanium Transceiver MMIC operating from 24.0 GHz up to 24.25 GHz. It is
based on a 24 GHz fundamental voltage controlled oscillator (VCO). A built in voltage source delivers a VCO
tuning voltage (V_PTAT) which is proportional to absolute temperature. When connected to the VCO tuning pin
(V_TUNE) it compensates for the inherent frequency drift of the VCO over temperature thus stabilizing the VCO
within the ISM band eliminating the need for a PLL/Microcontroller. An integrated 1:16 frequency divider also
allows for external phase lock loop VCO frequency stabilization.
The receiver section uses a low noise amplifier (LNA) in front of a quadrature homodyne down conversion mixer
in order to provide excellent receiver sensitivity. Derived from the internal VCO signal, a RC polyphase filter
(PPF) generates quadrature LO signals for the quadrature mixer. The I/Q IF outputs are available through a
single ended terminal respectively.
The device is manufactured in a 0.18μm SiGe:C technology offering a cutoff frequency of 200 GHz. It is
packaged in a 16 pin leadless RoHs compliant TSNP package.
