Introduction

The SKY66289-11 is a high-efficiency fully input / output matched power amplifier (PA) with high gain and linearity. The compact 5×5 mm PA is designed for FDD and TDD 2G/3G/4G LTE small cell base stations operating in two frequency ranges: 791 to 821 and 750 to 850 MHz. The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation. The SKY66289-11 is part of high efficiency, pin-to-pin compatible PA family supporting all 3GPP bands.

Features

• High efficiency: PAE = 35.5% @+28 dBm
• High linearity: +28 dBm with <-50 dBc linearized ACLR (20 MHz LTE, 8.5 dB PAR signal)
• High gain: 36.5 dB
• Excellent input and output return loss: to 50 Ω system
• Integrated active bias: performance compensated over temp
• Integrated enable ON / OFF function: PAEN = 1.7 to 2.5 V
• Single supply voltage: 5.0 V
• Pin-to-pin compatible PA family supporting all 3GPP bands
• Compact (16-pin, 5×5×1.3 mm) package (MSL3, 260 °C per JEDEC J-STD-020)

Applications

• FDD and TDD 2G/3G/4G LTE systems
• 3GPP Bands 20, 28, and 68 small-cell base stations
• Driver amplifier for micro base stations and macro base stations
• Active antenna array and massive MIMO
