Features
High-efficiency: PAE = 29% @ +28 dBm
Description
High linearity: +28 dBm with < 50 dBc ACLR with
pre-distortion (2 x 20 MHz LTE, 8.5 dB PAR signal)
The SKY66293-21 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 from 3400 to 3800 MHz. The active
biasing circuitry is integrated to compensate PA performance over
temperature, voltage, and process variation.
High gain: 35 dB
Excellent input and output return loss: to 50 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
The SKY66293-21 is part of high-efficiency, pin-to-pin compatible
PA family supporting all 3GPP bands.
Pin-to-pin compatible PA family supporting all 3GPP bands
A block diagram of the SKY66293-21 is shown in Figure 1. The
device package and pinout are shown in Figure 2. Table 1 lists
the pin-to-pin compatible parts in the PA family. Signal pin
assignments and functional pin descriptions are described in
Table 2.
