General Description
RAM-6A+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable per-
formance from lot to lot. It is enclosed in a ceramic surface-mount package. RAM-6A+ uses Darlington
configuration and is fabricated using GaAs technology.

Description
RF IN

RF input pin. This pin requires the use of an external DC blocking capacitor chosen
for the frequency of operation.
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.
a. The RAM-6A+part number is a potential replacement for the MSA-0636 part number based on a comparison of data and characterization information available for the MSA-0636 versus similar data and
the measured performance of RAM-6A+; the final determination of whether this RAM-6A+ part number is suitable 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 MSA-0636 part number is used for identification and comparison purposes only.
c. Avago Technologies is a registered trademark of Avago Technologies and is in no way affiliated with Mini-Circuits.
d. Data in Table for the MSA-0636 was taken from Avago Technologies published datasheet April 12, 2007and is used solely for informational purposes to identify MSA-0636
