DATA SHEET SKY65045-70LF: 390 to 1500 MHz Low-Noise Power Amplifier Driver Applications Description Skyworks SKY65045-70LF is a high performance, ultra-wideband UHF television Power Amplifier (PA) driver with superior output power, low noise, TETRA radio linearity, and efficiency. The device provides a 1.6 dB Noise GSM, AMPS, PCS, DCS, 2.5G, 3G Figure (NF) and an output power at 1 dB compression of +25 dBm, making the SKY65045-70LF ideal for use in the driver ISM band transmitters stage of infrastucture transmit chains. Fixed WCS The SKY65045-70LF is fabricated with Skyworks high reliability 802.16 WiMAX Heterojunction Bipolar Transistor (HBT) process. The device uses 3GPP Long Term Evolution 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 Features populated Evaluation Board is available upon request. Wideband frequency range: 390 to 1500 MHz The device package and pinout are shown in Figure 1. A Low Noise Figure: 1.8 dB functional block diagram is provided in Figure 2.
