TRF2443 Integrated IF Transceiver Evaluation Module

This document provides an easy guide for evaluating the TRF2443 integrated IF transceiver for broadbandwireless applications. Included in this guide are equipment setup procedures, software GUI configurations,and test procedures that allow a user to quickly and accurately measure the TRF2443 performance.

The TRF2443 is a fully integrated IF transceiver operating at a transmitter IF of 340 MHz (or 170 MHz)and a receiver IF of 140 MHz (or 280MHz). The IF transceiver is used to for up-conversion of signals fromthe transmit chain digital-to-analog convertor (DAC) to the RF upconverter device and fordown-conversion of received IF signals to baseband for processing by the analog-to-digital convertor(ADC). The receiver allows for switching in an external SAW filter if needed or by-passing this filter andprocessing the signal completely internally. The TRF2443 also provides an Auxiliary Receiver which canbe used for cross-polarization interference cancellation (XPIC). This document describes how to test theTRF2443 as well as the many options for trimming the device configuration to meet your applicationneeds.

EVM Circuit Overview

www.ti.com

The TRF2443 EVM requires a 3.3V dc power-supply connected to between J1 (3.3V) and J2 (GND). TheTRF2443 allows for analog or digital control of the transmitter power supply. Pin 1 (TXPWD) of the deviceprovides the analog control and is connected to header JP1 (TXPWD) on the EVM. When pins 1 and 2 ofheader JP1 are shorted, 3.3V is fed to the TXPWD pin and the transmitter is disabled. When pins 2 and 3of header JP1 are shorted, 0V is fed to the TXPWD pin and the transmitter is enabled (see Figure 2 andFigure 3 ). With header JP1 enabling the transmitter, it is still possible for the transmitter to be off due tothe state of the digital TX control.

EVM Circuit Overview

The TRF2443 EVM allows for either an external reference chosen by the user or an internal oscillator at20 MHz provided on the EVM board. If an external reference is to be used the signal should be fed intoSMA connector J3 (EXTREF) and jumpers W1 and W12 should be removed (see Figure 4 ).

Figure 4. EVM Reference Clock J3 and USB Port J5

The EVM is equipped with USB communications which provide the interface between a computer's USBport and the TRF2443s SPI port via J5 as shown in Figure 4 . A CD containing the GUI to control theTRF2443 is provided within the EVM kit. An overview of the GUI is provided in this document

The EVM is configured for differential I/Q input signals via four SMA connectors. For the upper sideband,the I signals are connected to J12 (TXBBIP) and J17 (TXBBIN). The Q signals are connected to J23(TXBBQN) and J20 (TXBBQP) (see Figure 5 ). SMA connector J6 (TXOUT), not shown below, is used tomonitor the RF output signal from the transmitter.

The EVM is configured for single ended RX input signal via SMA connector J7 (RXIN). This input is takenthrough a 1:1 balun to provide differential inputs to the device. The device presents 50 so no externaltermination resistor is required.

EVM Circuit Overview

The baseband I/Q signals can be measured balanced or unbalanced. The I output is taken from theunbalanced port J15 (RXBBI) through balun T5 or from the balanced ports of J13 (I+) and J18 (I-).Likewise, the Q output is taken from the unbalanced port J24 (RXBBQ) through balun T7 or the balancedports of J21 (Q+) and J26 (Q-). For balanced mode measurements, jumpers W3, W5, W7 and W9 mustbe removed.

EVM Circuit Overview

The TRF2443 RX path allows the use of an external SAW filter. An internal switch, which is programmablethrough the serial interface, gives the flexibility to utilize the external filter (see Figure 1 ). The internalswitch is controlled via the serial programming interface through bit EN_SAW. By programming EN_SAWto 1, the external path is selected, whereas a 0 engages the internal bypass switch. When EN_SAW is setto 1 the IF signal will be routed out of the IC to SMA connector J30 (IFOUT) (see Figure 8 ). At this point,the user has the flexibility to insert a filter of choice outside the TRF2443 EVM. (The board does contain aplace holder (FL1) for a SAW filter but is not populated. In this way, the user has the flexibility to use afilter of his choice). For initial evaluation, an 8-10 dB pad can be used in lieu of a filter to emulate theinsertion loss of a typical filter. The user must route the signal from J30 (IFOUT) to J31 (IFIN) with the filteror pad included.

1.6 XPIC Receiver

EVM Circuit Overview

The TRF2443 provides an auxiliary receiver chain that can be used for cross-polarization interferencecancellation purposes. The EVM is configured for a single-ended output signal (intended for the secondaryXPIC RX path) at J33 (XPICOUT). The input to the XPIC receiver (from the XPICOUT of the secondaryXPIC RX path) is available at SMA connector J32 (XPICIN). This input is taken through a 1:1.5 balun toprovide differential inputs to the device. The device presents 75 so no external termination resistor isrequired. The XPIC baseband I and Q signals can be measured balanced or unbalanced. The I output istaken from the unbalanced port J16 (XPICI) through balun T6 or from the balanced ports of J14 (I+) andJ19 (I-). Likewise, the Q output is taken from the unbalanced port J25 (XPICQ) through balun T8 or thebalanced ports of J22 (Q+) and J27 (Q-). For balanced mode measurements, jumpers W4, W6, W8, andW10 must be removed (see Figure 9 ).
