Targeting he TRF372017 IQ modulator integrates a direct upconversion IQ modulator with a PLL and wideband VCO to simplify local oscillator (LO) design and reduce board space. The part provides an ...

The TRF370317 IQ modulator enables conversion from baseband or intermediate frequency directly to RF frequencies. The part meets the stringent requirements of GSM, CDMA2000, TD-SCDMA, W-CDMA, and ...

Testing transceiver and converter interfaces requires orthogonal in-phase and quadrature (IQ) analog signals; that is, the phase relationship of the two must be very close to a 90-degree phase offset, ...
