LMA417
MEDIUM POWER PHEMT MMIC
• DESCRIPTION AND APPLICATIONS
The Filtronic Solid State LMA417 is a 3-stage medium power PHEMT amplifier that provides 19dB
linear power gain with 1-dB gain compression power output of greater than +21dBm for commercial
mm-W (millimeter-wave) 18 & 23GHz PCN/PCS and 20GHz SatCom application. Ground is
provided to the circuitry through vias to the backside metallization.
• ELECTRICAL SPECIFICATIONS @ T_Ambient = 25°C
(V_DD = +4.0V, Z_IN = Z_OUT = 50Ω)
