Product Data Sheet August 5, 2008 77 GHz Transceiver Switch TGS4307 Key Features I/O Compatible with MA4GC6772 3 Antenna Ports Receive, Source, and LO Ports 2.5 dB RX/TX Insertion Loss Typical 40 dB Source/Mixer Isolation Typical 25 dB Ant/Ant Isolation Typical Bias Supply: 1.3V 40mA Die Size: 1.70 x 2.16 x 0.1 mm Primary Applications Automotive Radar Instrumentation Radar Application Schematic Product Description The TGS4307 is a 77 GHz switch matrix for J2 use in automotive radar transceivers. The TGS4307 switch is designed using TriQuints proven B2 VPIN diode production process. J3 J1 B1 B3 Three antenna ports may be selected J4 independently and directed to a source (J5) J5 RX Port or a receive (J4) port. Additionally, the B5 B4 source port can be directed to the LO port Source B4 for use with a downconverting mixer.
