SKY66184-11: 2110 to 2170 MHz Linear Power Amplifier
Applications
Description
SKY66184-11 is a high-linearity power amplifier (PA) with fully
matched input/output and high gain. The compact 5 x 5 mm PA is
designed for FDD 3G/4G LTE small cell base stations operating
from 2100 to 2200 MHz. The active biasing circuitry is integrated
to compensate PA performance over temperature, voltage, and
process variation as well as an internal coupler for power
monitoring.
3G/4G LTE Band 1, 4, and 10 small cell
Active distributed antenna system

Features
The SKY66184-11 requires minimal external components and is
part of a high-linearity, pin-to-pin compatible PA family
supporting all 3GPP bands.
High gain: 39.0 dB (unconditionally stable)
High linearity: +23 dBm with –50 dBc ACLR @ 85°C
(WCDMA Test Model 1 with 64 DPCH)
A block diagram of the SKY66184-11 is shown in Figure 1. The
device package and pinout for the 28-pin device are shown in
Figure 2. Table 1 lists the pin-to-pin compatible parts in the PA
family.
RF input and output internally matched to 50
Excellent output return loss: < –17 dB
Integrated active bias: performance compensated over temp
PA On/Off function: 2.5 μs switching time
Integrated coupler for output power monitoring
Single supply voltage: 3.3 V
