RF Micro Devices has introduced the first in a line of integrated configurable components delivering high levels of flexibility and functional integration to designers of radio systems.

The first products in this category include RFMD's RF2051, RF2052 and RF2053. The RF205x line of integrated configurable components integrate common RF functions while retaining the flexibility designers require to develop radio systems that operate over a wide dynamic range and across a broad range of frequencies and channel bandwidths.

Applications include multiple radio markets, including wireless repeaters, software defined radios (SDR), professional mobile radios and instrumentation and test equipment.

Each product in the RF205x line is able to generate a broad LO signal range (300MHz to 2.4GHz) and operate over a broad RF/IF range (100MHz to 2.5GHz). The LO, which consists of the VCO and PLL, has an adjustable loop bandwidth that is set by a passive or active loop filter, allowing designers to optimize performance in wideband and narrowband applications. Each product offers an operational amplifier on-chip to eliminate the need for an external amplifier in active loop configurations.

The mixer linearity is programmable up to +18dBm, at which the mixer, PLL and VCO consume 72mA from a 3V supply. For applications with lower linearity requirements, current consumption can be reduced, allowing radio designers to trade off performance and current.

The RF2051, RF2052 and RF2053 are housed in a compact 5mm x 5mm QFN package. Price starts from $6.78 for RF2053 for 1,000-unit quantities.
