CML adds up/down converter to RF Building Block IC range

CML Microcircuits has added the CMX975 2.7GHz up/down converter to its RF Building Block IC range.

The CMX975 is an enabler for small form factor high frequency RF transceiver designs, operating up to 2.7GHz, that require high performance and low power consumption, says CML. It is supplied in a small form factor, yet integrates up and down conversion mixers and associated frequency generation circuitry. The CMX975 can reduce the number of external components required to configure a complete system. 

The up/down converter features programmable operation, allowing the designer to fully optimise the system design, explains CML. Both receive and transmit mixers can be selected to operate as a double balanced mixer stage or as image cancelling 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 voltage controlled oscillator is also integrated to provide an IF local oscillator for superhet architecture operation.

The CMX975 has programmable power management functionality, controlled via a SPI-compatible serial bus, operates from a single 2.7 to 3.6V power supply and is available in a small outline VQFN package.

The device is designed for use in mobile satellite services, military communications, aircraft surveillance systems, high performance industrial, scientific and medical (ISM) radio applications and general purpose RF/IF communication systems.

CML Microcircuits designs, develops and supplies RF, low-power analogue, digital, and mixed-signal semiconductors for wireless communications systems globally.

It has ISO 9001: 2008 certified design, production and marketing facilities and network of over one-hundred accredited distributors and representatives around the world.

CML is supportive of conserving the natural environment and aims to manage its operations in ways that are environmentally friendly and economically viable. CML provides RoHS compliant, lead-free (Pb-free) products.
