The innovative RF205x line of integrated configurable components integrate common radio frequency 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.
The RF205x line of integrated configurable components are broadly applicable to multiple radio markets, including wireless repeaters, software defined radios (SDR), professional mobile radios and instrumentation and test equipment.
The RF2051 combines a wideband monolithic voltage controlled oscillator (VCO), local oscillator (LO) drivers, a fractional-N phase locked loop (PLL) synthesiser and two RF mixers, and can be configured as a monolithic upconvertor and downconvertor, making it ideal for uplink and downlink chains in applications such as wireless repeaters and as self-contained frequency band-shifters.

Single-chip Bluetooth improves coexistence
The SiW3500 UltimateBlue IC is a complete single-chip CMOS Bluetooth solution.
The RF2052 leverages the configurable core of the RF2051 (integrated VCO, PLL and LO drivers), combines a wideband monolithic voltage controlled oscillator (VCO), LO drivers, a fractional-N PLL synthesiser and one RF mixer, and can be configured as either an upconvertor or downconvertor for applications requiring separate up and down conversion stages.
And the RF2053 leverages the configurable core of the RF2051 (PLL and LO drivers) and combines LO drivers, a fractional-N PLL synthesiser, one RF mixer and uses an external VCO source.
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 optimise performance in wideband and narrowband applications.
Finally, 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 just 72mA from a 3-volt supply.
For applications with lower linearity requirements, current consumption can be reduced, allowing radio designers to trade off performance and current.
This is particularly important in applications requiring lower current consumption, including portable battery-powered devices.
According to Alastair Upton, General Manager of RFMD's Broadband and Consumer Business Unit: "RFMD is committed to providing valuable innovations that support our customers' success".
"The unique system partitioning and functional integration of the RF205x line of integrated configurable components helps radio designers across multiple industries improve competitiveness by shrinking circuit board area, reducing risk and shortening product development time, thereby lowering the cost of implementation".
The RF2051, RF2052 and RF2053 are housed in compact 5 x 5mm QFN packages, and samples are available immediately.
