SKY66397-12: 2300 to 2700 MHz Wide Instantaneous
Bandwidth High-Efficiency Power Amplifier
Applications
Description
The SKY66397-12 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 2300 to 2700 MHz. The active
biasing circuitry is integrated to compensate PA performance over
temperature, voltage, and process variation.
FDD and TDD 2G/3G/4G LTE systems
3GPP bands 7, 38, and 41 small-cell base stations
Driver amplifier for micro-base and macro-base stations
Active antenna array and massive MIMO
The SKY66397-12 is part of high-efficiency, pin-to-pin compatible
PA family supporting all 3GPP bands. Table 1 lists the pin-to-pin
compatible parts in the PA family.
Features
High-efficiency: PAE = 35% @ +28 dBm
A block diagram of the SKY66397-12 is shown in Figure 1. The
device package and pinout for the device are shown in Figure 2.
Signal pin assignments and functional pin descriptions are
described in Table 2.
High linearity: +28 dBm with < -50 dBc ACLR with
pre-distortion (40 MHz LTE, 8.5 dB PAR signal)
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 = 1.5 to 2.5 V
Single supply voltage: 5.0 V
