Description
SKY66297-11 is a high-efficiency fully input/output matched
High gain: 32.5 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
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 2490 to 2690 MHz. The active
biasing circuitry is integrated to compensate PA performance over
temperature, voltage, and process variation.
Pin-to-pin compatible PA family supporting all 3GPP bands
The SKY66297-11 is part of high-efficiency, 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)
A block diagram of the SKY66297-11 is shown in Figure 1.
Table 1 lists the pin-to-pin compatible parts in the PA family. The
device package and pinout are shown in Figure 2. Signal pin
assignments and functional pin descriptions are described in
Table 2.
