simplified schematic and pin description
Function Pin Number Description
RF IN 1RF 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-7+ (RoHS compliant) is a wideband amplier offering high dynamic range. It has repeatable perfor-
mance from lot to lot. It is enclosed in a ceramic surface-mount package. RAM-7+ uses Darlington con-
guration and is fabricated using InGaP HBT technology. Expected MTBF is 3700 years at 100°C case
temperature.
