MAR-8ASM+
CASE STYLE: WW107
+RoHS Compliant
The +Suffix identifies RoHS Compliance. See our web site
for RoHS Compliance methodologies and qualifications
Typical Applications
• Cellular
• PCN instrumentation
General Description
MAR-8ASM+ (RoHS compliant) is a wideband amplifier offering high dynamic range.
It has repeatable
performance from lot to lot.
It is enclosed in a Micro-X package.
MAR-8ASM+ uses Darlington configura
–
tion and is fabricated using InGaP HBT technology.

Function
Pin Number
Description
RF input pin. This pin requires the use of an external DC blocking capacitor chosen for
the frequency of operation.
RF IN
1
RF output and bias pin.
DC voltage is present on this pin; therefore a DC blocking
capacitor is necessary for proper operation.
An RF choke is needed to feed DC bias
without loss of RF signal due to the bias connection, as shown in “Recommended
Application Circuit”.

Connections to ground.
Use via holes as shown in “Suggested Layout for PCB Design”
to reduce ground path inductance for best performance.

Notes:
a. Suitability for model replacement within a particular system must be determined by and is solely the responsibility of the customer based on, among other things, electrical performance
criteria, stimulus conditions, application, compatibility with other components and environmental conditions and stresses.
b. The Avago MSA-0885 part number is used for identification and comparison purposes only.
