RF Micro Devices RFFC0085 frequency converter integrated circuit

RF Micro Devices has introduced the RFFC0085 frequency converter integrated circuit (IC).

The CMOS-based frequency converter IC is designed for use as an out-of-band receive circuit tuner in cable industry and SATCOM-DBS set-top boxes, DOCSIS set-top gateways, OpenCable Application Platform CableCards, Tru2Way products and CableCard-equipped HDTVs.

The device consists of an input AGC amplifier, mixer and a video/AGC amplifier and has good performance, low power consumption and low distortion. It is claimed to give a >50% reduction in DC power dissipation and a 55% or greater reduction in printed circuit board assembly. Combined with +3.3 VDC, it operates with higher conversion gain and lower DC power dissipation than +5 VDC tuners, with a low external component count.
