General Description
Mimix Broadband’s two stage 2.0-18.0 GHz GaAs MMIC
low noise amplifier has a small signal gain of 18.0 dB
with a noise figure of 3.5 dB across the band. This MMIC
uses Mimix Broadband’s 0.3 µm GaAs PHEMT device
model technology, and is based upon optical
lithography to ensure high repeatability and uniformity.
The chip has surface passivation to protect and provide
a rugged part with backside via holes and gold
metallization to allow either a conductive epoxy or
eutectic solder die attach process. This device is well
suited for fiber optic, microwave radio, military, space,
telecom infrastructure, test instrumentation and VSAT
applications.

App Note [1] Biasing
- As shown in the bonding diagram, this device operates using a self-biased architecture and only requires one drain
bias. Bias is nominally Vd1=Vd2=5V, I
TOTAL
=105mA. Additionally there are six total source resistors on chip. The three resistors on the input
stage are 16.6, 29.0 and 29.0 Ohms. The three resistors on the output stage are 12.5, 12.5 and 9.0 Ohms. One of these must be bonded to
ground for each amplifier stage to achieve performance as shown. Bonding to one of the other resistors or any or all in parallel may allow
additional performance adjustment. Lastly for additional stability pad #3 can be grounded instead of bond pad #2.
App Note [2] Bias Arrangement
- Each DC pad (Vd) needs to have DC bypass capacitance (~100-200 pF) as close to the device as possible.
Additional DC bypass capacitance (~0.01 uF) is also recommended.
