390–1500 MHz Low Noise Power Amplifier Driver

Skyworks SKY65045-70LF is a high-performance, ultrawideband Power Amplifier (PA) driver with superior output power, low noise, linearity, and efficiency. The device provides a 1.6 dB Noise Figure (NF) and an output power at 1 dB compression of 25 dBm, making the SKY65045-70LF ideal for use in the driver stage of infrastructure transmit chains. The SKY65045-70LF is fabricated with Skyworks high reliability Heterojunction Bipolar Transistor (HBT) process. The device uses low-cost Surface Mount Technology (SMT) in the form of a 2.4 x 4.5 mm Small Outline Transistor (SOT-89) package. The module can operate over the temperature range of -40 °C to +85 °C. A populated evaluation board is available upon request.

Please note: SKY65045-70LF is being discontinued and is not recommended for new designs. The suggested replacement are SKY65173-70LF or SKY65162-70LF.
