Product Information
High Dynamic Range Dual Amplifier
Product Description
The AH11 is a high linearity amplifier for use in digital
communication systems. It combines low noise figure and
high intercept point into a low-cost SMT solution. This
device extends the linear efficiency advantages of WJ’s AH1
to higher power levels by combining two internally matched
die. This dual-amplifier configuration allows for the optimal
design of balanced or push-pull operation. The amplifier
can also be used for single-ended operation in each branch
of a diversity receive system.
A mature and reliable GaAs MESFET technology is
employed to maximize linearity while achieving low noise
figure. The package is a thermally enhanced lead-free/
green/RoHS-compliant SOIC-8 package thus allowing the
device to achieve an MTTF greater than 100 years at a case
temperature of 85
°C.
All devices are 100% RF and DC
tested.

Typical Performance
(Dual P-P Configuration)
1. Test conditions unless otherwise noted: T = 25 ºC, Supply Voltage = +5 V, Frequency = 800 MHz,
50
Ω
System, tested on each single-ended amplifier (there are two amplifiers in an AH11 package)
2. S21 and S11 can be improved in the band of interest with some slight input tuning.
3. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule. Slight OIP3
degradation of about 2 dB is expected to occur at lower temperatures (from 25 ºC to –40 ºC).
