TRF371135EVM
概要
The TRF371135EVM is the evaluation module for the TRF371135 device. The TRF371135 is a direct conversion quadrature demodulator which integrates programmable baseband filters, adjustable DC offset correction, and output buffer amplifiers for driving high speed ADCs. The TRF371135 is suited for operation with WCDMA, CDMA200, WiMAX and LTE modulation as well as with other high bandwidth signal modulation schemes. The TRF371135 is designed to support wireless communications applications that require excellent wideband receiver RF performance (linearity and sensitivity) and flexibility, but with a reduced form factor.
特長
The TRF371135EVM is used to test the performance of the TRF371135 direct quadrature demodulator device. The RF input and LO (local oscillator) input require differential signals, achieved with the use of an RF balun. The TRF371135EVM can be configured with different baluns to facilitate operation in the frequency band of interest. The input signal is injected into the RFin connector (J6). After it is transformed into a differential signal by a balun it is fed into the TRF371135 input ports. The local oscillator source is connected to the LO port (J7) and through a similar balun it is differentially injected into the TRF371135 LO pins. The input signal after being down-converted and filtered by the TRF371135 can be tested at the baseband output ports both single-ended or differentially.

Overview
The RF Cascade Calculator is a web-based tool for performing RF signal chain (lineup) cascade analysis. It computes cascaded performance parameters across a multi-stage RF signal chain using standard cascade equations (Friis formula for noise figure, reciprocal power sums for IP3/IP2/P1dB, etc.).
The tool is hosted on the TI Developer Gallery and runs entirely in the user's browser — no software download or installation is required.
