RFMD adds low-power IQ modulators with Integrated local oscillators

RF Micro Devices Inc of Greensboro, NC, USA has extended its portfolio of broadband components to include two new low-power IQ modulators featuring integrated fractional-N synthesizers and voltage controlled oscillators (VCO).

The RFMD2080 and RFMD2081 are broadband devices capable of generating output frequencies from 45MHz to 2700MHz. They suit a wide range of applications including satellite communications, point-to-point radio, software-defined radio, and other wireless and wireline applications requiring QPSK/QAM modulators. The broadband nature of the components and the integration of the local oscillator offer a competitive combination of functionality, versatility, and size, claims RFMD.

The RFMD2080 features a baseband interface incorporating programmable filtering and gain control. Optimized for low-power operation, current consumption is just 150mA from a 3V supply, allowing the creation of more environmentally friendly systems with reduced power consumption, it is claimed. Both the RFMD2080 and RFMD2081 are programmable using a simple 3-wire serial interface and offered in QFN 5mm x 5mm packages.

“RFMD’s new IQ modulator products significantly reduce implementation size and complexity, power consumption and cost,” claims Alastair Upton, general manager of the firm’s Broadband Components business unit. The new devices leverage RFMD’s optimal technology matching (OTM) strategy, he adds.

RFMD is exhibiting the components in booth 1402 at next week’s IEEE International Microwave Symposium (IMS 2011) in Baltimore, MD, USA (6–8 June).
