Product Description
Sirenza Microdevices SNA-286 is a GaAs monolithic broad-
band amplifier (MMIC) housed in a low-cost surface-mount-
able plastic package. At 1950 MHz, this amplifier provides
15.5dB of gain and +14dBm of P1dB power when biased at
50mA.
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-200), its small size (0.33mm
x 0.33mm) and gold metallization make it an ideal choice for
use in hybrid circuits.
