SNA-376 Product Description Sirenza Microdevices SNA-376 is a GaAs monolithic broadband amplifier (MMIC) housed in a low-cost surface mountable stripline package. This amplifier provides 22dB of gain when biased at 35mA. External DC decoupling capacitors determine low frequency response. The use of an external resistor allows for bias flexibility and stability. These unconditionally stable amplifiers are designed for use as general purpose 50 ohm gain blocks. Also available in chip form (SNA-300), its small size (0.33mm x 0.33mm) and gold metallization make it an ideal choice for use in hybrid circuits.

Simplified Schematic of MMIC Part Identification Marking The part will be marked with an S3 designator on the top surface of the package. 4 1 S3 Pin # Function 1 RF IN RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. 2, 4 GND Connection to ground. For optimum RF performance, use via holes as close to ground leads as possible to reduce lead inductance. 3 3 2 Description 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.
