simplified schematic and pin description
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”.
GROUND 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 24+ (RoHS compliant) is a wideband amplifier offering high dynamic range. Lead finish is SnAgNi.
It has repeatable performance from lot to lot and is enclosed in a SOT-89 package. It uses patented
Transient Protected Darlington configuration and is fabricated using InGaP HBT technology. Expected
MTBF is 2750 years at 85°C case temperature. Gali 24+ is designed to be rugged for ESD and supply
switch-on transients.

Evaluation Board and Circuit
BOM of Evaluation Board
Notes:
1. Vcc may be any voltage from +12 to +24V
2. Parallel combination of R1, R2, R3 (sets bias current). Each is a 0805-size chip rated at 1/8W.
3. SMA Female connectors
4. PCB material: Rogers RO4350 or equivalent, dielectric constant=3.5, dielectric thickness= .030 inch.
5. Capacitors, C1&C2 should be free of resonance up to the highest frequency specified.
