TRF3701数据手册RF/IF射频/中频RFID的RF调制器规格书PDF

描述 Description

The TRF3701 is an ultralow-noise directquadrature modulator that is capable of converting complex input signals from baseband or IF directly up to RF. An internal analog combiner sums the real and imaginary components of the RF outputs. This combined output can feed the RF preamp directly at frequencies of up to 1.5 GHz. The modulator is implemented as a double-balanced mixer. An internal local oscillator (LO) phase splitter accommodates a single-ended LO input, eliminating the need for a costly external balun.
