Description

Skyworks SKY65045-70LF is a high performance, ultra-wideband

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 infrastucture 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 a temperature range of -40 °C to +85 °C. A

populated Evaluation Board is available upon request.

The device package and pinout are shown in Figure 1. A

functional block diagram is provided in Figure 2.
