PRODUCT DESCRIPTION
The ALT5020 PA is designed to provide highly linear
output for LTE handsets and data devices with high
efficiency at high power mode. This ANADIGICS PA
can be used with an external switch mode power VBATT
supply (SMPS) to improve its efficiency and reduce
current consumption further at high and low output
powers. The device is manufactured on an advanced
RFIN
InGaP HBT MMIC technology offering state-of-theart reliability, temperature stability, and ruggedness.
There are three selectable bias modes that optimize
efficiency for different output power levels, and a
shutdown mode with low leakage current, which VMODE2
increases handset talk and standby time. The selfcontained 3 mm x 3 mm x 0.9 mm surface mount
package incorporates matching networks optimized for
VMODE1
output power, efficiency, and linearity in a 50 Ω system.

The device may be operated safely over these conditions; however, parametric performance is guaranteed only
over the conditions defined in the electrical specifications.
Notes:
(1) For operation at Vcc = +3.1 V, Pout is derated by 0.8 dB.
(2) For operation at 105 °C, POUT is derated by 1.0 dB.
(3) LTE waveform characteristics up to 20 MHz QPSK, 18 RB’s.

logic level (see Operating Ranges table) to VMODE1,2.
The Bias Control table lists the recommended modes
of operation for various applications.
Shutdown Mode
The power amplifier may be placed in a shutdown
mode by applying logic low levels (see Operating
Ranges table) to the VENABLE and VMODE voltages.
Three operating modes are available to optimize
current consumption. High Bias/High Power operating
mode is for POUT levels > 15 dBm. At around 16 dBm
output power, the PA should be “Mode Switched” to
Medium power mode for lowest quiescent current
consumption. The PA should be switched to Low Bias/
Low Power mode at ~<7 dbm.
Bias Modes
The power amplifier may be placed in either a Low,
Medium or High Bias mode by applying the appropriate
