The linear nature of the up-converter makes it ideal for complex modulations schemes such as high order QAM or OFDM. GND LOADJ2 GND LOP LON VDDLO GND GND The TRF1122 up-converts a UHF IF signal to an RF signal in the 2100-MHz to 2700-MHz range for 2.5-GHz radio applications. The TRF1122 has 20 dB of gain and an output P-1 dB of +14 dBm, typical. A TTL compatible, 1-bit 16-dB switched attenuator is provided for gain control and the IF and RF amplifiers can be shut off via a TTL control signal for power critical or TDD applications. In order to provide system requirements for LO/spurious rejection, the TRF1122 offers a signal path to an off-chip band-pass filter. Specifications are provided assuming an in-band 2-dB insertion loss filter. P0042-01 Figure 1.
