Press Release Summary:
Housed in 5 x 5 mm QFN package, RF205x Series generates local oscillator signal range from 300 MHz to 2.4 GHz and operates over RF/IF range of 100 MHz to 2.5 GHz. Local oscillator, which consists of VCO and PLL, has adjustable loop bandwidth that is set by passive or active loop filter. On-chip op-amp eliminates need for external amplifier in active loop configurations. Mixer linearity is programmable up to +18 dBm, at which mixer, PLL, and VCO consume 72 mA from 3 V supply.

RFMD® Unveils Line of Integrated Configurable Components
Revolutionary New Product Category Delivers Superior Combination Of Flexibility And Functional Integration
GREENSBORO, N.C., April 9, 2008 /- RF Micro Devices, (NASDAQ:RFMD), a global leader in the design and manufacture of high-performance radio frequency systems and solutions, today introduced the first in a new line of integrated configurable components delivering unmatched levels of flexibility and functional integration to designers of radio systems.
The first products in this new category include RFMD's RF2051, RF2052 and RF2053. The innovative RF205x line of integrated configurable components integrate common radio frequency (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. 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.
Highlights of the RF205x line of integrated configurable components include:
-- Combines a wideband monolithic voltage controlled oscillator (VCO), local oscillator (LO) drivers, a fractional-N phase locked loop (PLL) synthesizer and two RF mixers
-- Can be configured as a monolithic upconverter and downconverter, making it ideal for uplink and downlink chains in applications such as wireless repeaters and as self-contained frequency band-shifters
-- 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 synthesizer and one RF mixer
-- Can be configured as either an upconverter or downconverter for applications requiring separate up and down conversion stages
-- Leverages the configurable core of the RF2051 (PLL and LO drivers)
-- Combines LO drivers, a fractional-N PLL synthesizer, one RF mixer and utilizes 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 optimize 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.
Alastair Upton, general manager of RFMD's Broadband and Consumer Business Unit, said, "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 a compact 5x5mm QFN package and samples are available immediately. For more information please see www.rfmd.com/RF205x.
