To enable high-frequency RF transceiver designs with small form factor and low power consumption,  CML Microcircuits has unveiled a new 2.7GHz Up/Down Converter. Applications can be seen in mobile satellite services (MSS), military communications, aircraft surveillance systems, high-performance ISM radio applications and general purpose RF/IF communication systems.

By integrating up and down conversion mixers and associated frequency generation circuitry, the CMX975 minimizes the number of external components required to configure a complete system.

The device features programmable operation, allowing the designer to fully optimize the system design. Both receive and transmit mixers can be selected to operate as a double balanced mixer stage or as image canceling mixers, intended to ease external filtering requirements and to lower overall system cost.

A flexible switching arrangement allows internal or externally sourced local oscillator signals and the main RF mixers to be driven from an external or integrated VCO.

The integrated Fractional-N PLL allows fine frequency resolution and fast frequency lock. An integer-N PLL and VCO is also integrated to provide an IF local oscillator for superhet architecture operation.

Other key features include programmable power management functionality, controlled via a SPI compatible serial bus, operation from a single 2.7-3.6V power supply and a small outline VQFN package.
