Skyworks launches HBT drive amplifier in 2mm QFN for cellular infrastructure

Skyworks Solutions Inc of Woburn, MA, USA, which manufactures analog and mixed-signal semiconductors, has launched a highly efficient, broadband, 13dB gain, gallium arsenide (GaAs) heterojunction bipolar transistor (HBT) drive amplifier in a small 2mm x 2mm QFN (quad flat, no lead) package.

The SKY67130-396LF draws less than 23mA at 3.3V, while achieving +39dBm OIP3 (output third-order intercept point), providing a high linearity solution. On-die active bias design ensures consistent performance and unconditional stability, the firm claims.

The cost-effective solution is suited to cellular infrastructure applications such as tower-mounted amplifiers, remote radio units, repeaters, and base stations, as well as WLAN and ISM-band applications at 2.45 and 0.9GHz, that require a highly efficient driver amplifier or low-power PA with moderate noise figure and low VSWR (voltage standing wave ratio).

Samples are available, and pricing depends on quantities.
