Preliminary Product Description SGA-2486 Stanford Microdevices' SGA-2486 is a high performance cascadeable 50-ohm amplifier designed for operation at voltages as low as 2.7V. This RFIC uses the latest Silicon Germanium Heterostructure Bipolar Transistor (SiGe HBT) process featuring 1 micron emitters with FT up to 65 GHz. DC-2000 MHz Silicon Germanium HBT Cascadeable Gain Block This circuit uses a darlington pair topology with resistive feedback for broadband performance as well as stability over its entire temperature range. Internally matched to 50 ohm impedance, the SGA-2486 requires only DC blocking and bypass capacitors for external components.

This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. GND Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possible. RF OUT/ RF output and bias pin. DC voltage is BIAS present on this pin, therefore a DC blocking capacitor is necessary for proper operation.
