Description
The SKY66292-11 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 from 2300 to 2400 MHz. The active
biasing circuitry is integrated to compensate PA performance over
temperature, voltage, and process variation.
The SKY66292-11 is part of high efficiency, pin-to-pin compatible
PA family supporting all 3GPP bands.
A block diagram of the SKY66292-11 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.

Description
1 The center ground pad must have a low inductance and low thermal resistance connection to the application’s printed circuit board ground plane.
Technical Description
The matching circuits are contained within the device. An on-chip
active bias circuit is included within the device for both input and
output stages, which provides excellent gain tracking over
temperature and voltage variations.
The SKY66292-11 is internally matched for maximum output
power and efficiency. The input and output stages are
independently supplied using the VCC1, VCC2, and VCC3 supply
lines (pins 16, 14, and 12, respectively). The DC control voltage
that sets the bias is supplied by the VCBIAS signal (pin 5).
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY66292-11 are provided
in Table 3. Recommended operating conditions are specified in
Table 4 and electrical specifications are provided in Table 5.
Typical performance characteristics are shown in Figures 3
through 16.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
ESD HANDLING:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.

1 RF turn-on time is measured from the time the PA enable reaches 50% of PA enable "on" level to the time at which the RF output power achieves 90% of the average steady-state “on” level.
RF turn-off time is measured from the time the PA enable reaches 50% of PA enable "on" level to the time at which the RF output power decreases to 10% of the average steady-state “on”
level.
