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 50Ωat 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.
