AVAGO ALM-31122 1-watt high linearity amplifier Datasheet

ALM-31122
700MHz - 1GHz
1-Watt High Linearity Amplifier
Data Sheet
Description
Features
Avago Technologies’ ALM-31122 is a high linearity 1 Watt
PA with good OIP3 performance and exceptionally good
PAE at 1dB gain compression point, achieved through the
use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process.
x Fully matched, input and output
All matching components are fully integrated within the
module. This makes the ALM-31122 extremely easy to use.
The adjustable temperature-compensated internal bias
circuit allows the device to be operated at either class A or
class AB operation.
The ALM-31122 is housed inside a miniature 5.0 x 6.0 x 1.1
mm3 22-lead multiple-chips-on-board (MCOB) module
package.
x High linearity and P1dB
x Unconditionally stable across load condition
x Built-in adjustable temperature-compensated internal
bias circuitry
x GaAs E-pHEMT Technology[1]
x 5V supply
x Excellent uniformity in product specifications
x Tape-and-Reel packaging option available
x MSL-3 and Lead-free
x High MTTF for base station application

Applications
x Class A driver amplifier for GSM/CDMA Base Stations.
x General purpose gain block.
Note:
1. Enhancement mode technology employs positive gate voltage,
thereby eliminating the need of negative gate voltage associated
with conventional depletion mode devices.
Attention: Observe precautions for
handling electrostatic sensitive devices.

Notes:
5. Distribution data sample size is 500 samples taken from 3 different
wafers. TA = 25°C, Vdd = 5V, Vctrl = 5V, RF performance at 900MHz
unless otherwise specified. Future wafers allocated to this product
may have nominal values anywhere between the upper and lower
limits.
6. Measurements are made on a production test board. Input trace
losses have not been de-embedded from actual measurements.
Electrical Specifications [7]
TA = 25 °C, Vdd =5V, Vctrl=5V, RF performance at 900MHz, measured on demo board (see Figure 7) unless otherwise
specified.

Notes:
7. Measurements at 900MHz obtained using demo board described in Figure 6 and 7.
8. 900MHz OIP3 test condition: FRF1 - FRF2 = 10MHz with input power of -5dBm per tone measured at worse case side band.
9. Use proper bias, heat sink and de-rating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and
application note (if applicable) for more details.
