TRF3703

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

The TRF3703 is a very low-noise direct quadrature modulator, capable of converting complex modulated signals from baseband or IF directly up to RF. The TRF3703 is ideal for high-performance direct RF modulation from 400 MHz up to 4 GHz. The modulator is implemented as a double-balanced mixer. The RF output block consists of a differential to single-ended converter and an RF amplifier capable of driving a single-ended 50-W load without any need of external components. The TRF3703 comes in two types, TRF370333 and TRF370315. The RF370333 and TRF370315 devices have different common-mode voltage ratings at the I, Q baseband inputs.

The TRF370333 requires a 3.3-V common-mode voltage, and the TRF370315 requires a 1.5-V common-mode voltage.
