AMMP-6231
18 to 32 GHz GaAs Low Noise Amplifier
Data Sheet
Description
Avago Technologies AMMP-6231 is a high gain, low-noise
amplifier that operates from 18 GHz to 32 GHz. It has a
3 dB noise figure, over 20 dB of gain and designed to
be an easy-to-use drop-in with any surface mount PCB
application. Popular applications include microwave ra-
dios, 802.16 and satellite VSAT or DBS receivers. The fully
integrated microwave circuit eliminated the complex tun-
ing and assembly processes typically required by hybrid
(discrete-FET) amplifiers. The surface mount package
allows elimination of “chip & wire” assembly for lower
cost. The device has 50 Ω input and output match and
is unconditionally stable. The MMIC has fully integrated
input and output DC blocking capacitors and bias choke.
The backside of the package is both RF and DC ground
that simplifies the assembly process. It is fabricated in
a PHEMT process to provide exceptional low noise and
gain performance.

Note: These devices are ESD sensitive. The following precautions are strongly recommended. Ensure
that an ESD approved carrier is used when units are transported from one destination to another. Per-
sonal grounding is to be worn at all times when handling these devices. The manufacturer assumes no
responsibilities for ESD damage due to improper storage and handling of these devices.

Biasing and Operation
The AMMP-6231 is normally biased with a positive drain
supply connected to the VDD pin through a 0.1uF bypass
capacitor as shown in Figure 13. The recommended drain
supply voltage is 3V. It is important to have 0.1uF bypass
capacitor, and the capacitor should be placed as close to
the component as possible. Input and output ports are
DC-blocked. Impedance matching at input and output
ports are achieved on-chip, therefore, no extra external
component is needed. Aspects of the amplifier perfor-
mance may be improved over a narrower bandwidth by
application of additional conjugate, linearity, or low noise
(Gopt) matching No ground wires are needed because
all ground connections are made with plated through-
holes to the backside of the package. This part is only
conditionally stable. There is a potential region of insta-
bility around 42GHz and particular care is needed with
the source and load impedances presented to the part
around this frequency to avoid oscillations, especially at
low operating temperatures.
