Function

Pin Number

Description

RF IN

1

RF input pin. This pin requires the use of an external DC blocking capacitor chosen

for the frequency of operation.

RF-OUT and DC-IN

3

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”.

GND

2,4

Connections to ground. Use via holes as shown in “Suggested Layout for PCB

Design” to reduce ground path inductance for best performance.

General Description

RAM-1+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable perfor-

mance from lot to lot. It is enclosed in a ceramic surface-mount package. RAM-1+ uses Darlington con-

figuration and is fabricated using InGaP HBT technology. Expected MTBF is 4,000 years at 100°C case

temperature.
