TRF2443IPFP

RF Misc ICS And Modules Overview

The TRF2443IPFP is an integrated intermediate frequency (IF) transceiver designed for broadband wireless applications, specifically WiMax. Manufactured by Texas Instruments, this component supports dual-band operation across two distinct frequency ranges: 140 MHz to 160 MHz and 280 MHz to 330 MHz. It is housed in a surface-mount 80-pin HTQFP package with an exposed pad, measuring 12x12 mm. The device operates at a supply voltage of 3.3V and features a terminal pitch of 0.5mm. It is classified as a telecom circuit with one function, utilizing a PQFP80 configuration for signal processing.
