The AH420 is a high dynamic range amplifier in a low-cost
surface mount package. The InGaP/GaAs HBT is able to
achieve high performance with -49 dBc ACLR and +35.7
dBm of compressed 1dB power, operating off of a single
+5V supply. It is housed in a lead-free/green/RoHS-
compliant 4x5mm DFN package. All devices are 100% RF
and DC tested.
The AH420 is targeted for use as a final stage amplifier in
wireless infrastructure repeaters or as driver stages for high
power amplifiers where high performance is required. In
addition, the amplifier can be used for a wide variety of
other applications within the 400 to 2700 MHz frequency
band. By operating off of a single +5V rail, other higher
voltage rails are not necessarily needed thus saving system
costs. The amplifier also has the flexibility to operate at
higher voltage levels to achieve higher compression if
needed by the system.

1. Test conditions unless otherwise noted: 25ºC, +5V Vsupply, 2140 MHz, in tuned application circuit.
2. W-CDMA 3GPP Test Model 1+64 DPCH, PAR = 10.2 dB @ 0.01% Probability, 3.84 MHz BW
3. This corresponds to the quiescent current under small-signal conditions into pins 6, 7, and 8 when
the current setting resistor, R4 connected to the Iref pin, is at 82 .
4. OIP3 is measured with two tones at out an output power of +27 dBm/tone separated by 1 MHz.
The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.

Circuit Board Material: 0.014” GETEK, single layer, 1 oz copper, εr = 4.2,
Microstrip line details: width = .030”, marker spacing = .050”
Notes:
1. Please note that for reliable operation, the evaluation board will have to be mounted to a
much larger heat sink during operation and in laboratory environments to dissipate the
power consumed by the device. The use of a convection fan is also recommended in
laboratory environments.
2. The area around the module underneath the PCB should not contain any soldermask in
order to maintain good RF grounding.
