RFMD launches analog-controlled VGA for 400-2700MHz broadband applications

RF Micro Devices Inc of Greensboro, NC, USA has launched the RFVA0016, an integrated, analog-controlled, variable-gain amplifier (VGA) for broadband applications with external matching, allowing operation in all bands from 400MHz to 2700MHz with a single module.

Operating from a +5V supply, the device features what is claimed to be exceptional linearity (OIP3 of greater than 40dBm), and provides a gain control range of more than 30dB. Gain is 25dB. A mode logic pin enables the VGA to be selected for either a 0V to +3V or a +3V to 0V analog-controlled attenuation slope. The adjacent channel power ratio (ACPR) is better than -60dBc at +10dBm POUT (for dual-carrier WCDMA).

The RFVA0016 is packaged in a small 5.2mm x 5.2mm leadless laminate multi-chip module (MCM) with thermal vias for ultra-low thermal resistance, and is externally matched to 50Ω at each individual band.

Applications include: cellular, 3G infrastructure; WiBro, WiMax, and LTE; microwave radio; and high-linearity power control.

The RFVA0016 is currently available in production quantities. Pricing begins at $8.72 each in 100-unit quantities.
