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
Gali 5+ (RoHS compliant) is a wideband amplier offering high dynamic range. Lead nish is SnAgNi. It
has repeatable performance from lot to lot, and is enclosed in a SOT-89 package. It uses patented Tran-
sient Protected Darlington conguration and is fabricated using InGaP HBT technology. Expected MTBF
is 3,000 years at 85°C case temperature. Gali 5+ is designed to be rugged for ESD and supply switch-on
transients.
