19 dB Gain
23 dBm Output Power at Saturation
14 dB Input/Output Return Loss
+4 V Dual Bias Supply
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.

ASSEMBLY DRAWING
Notes:
Recommended lead bond technique is thermocompression wedge bonding with 0.001" (25m) diameter wire. The
bond tool force shall be 35-38 gram. Bonding stage temperature shall be 230-240C, heated tool (150-160C) is
recommended. Ultrasonic bonding is not recommended.
The recommended die attach
is a eutectic 80/20 Gold/Tin solder, using a stage temperature of 285-290C
.
Bond on bond or stitch bond acceptable.
Conductor over conductor acceptable. Conductors must not short.

HANDLING PRECAUTIONS
To avoid damage to the devices care should be exercised during handling. Proper Electrostatic
Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and
testing. These devices should be treated as Class 1A (0-500 V). Further information on ESD control
measures can be found in MIL-STD-1686 and MIL-HDBK-263.
All information and specifications are subject to change without notice.
