GENERAL DESCRIPTION:
The FMA219 is a 2-stage, reactively matched pHEMT low-noise MMIC amplifier designed for use over 7.0 to 11.0 GHz. The amplifier requires a single +3V supply and one off-chip component for supply de-coupling. Both the input and output ports are DC de-coupled. Grounding of the amplifier is provided by plated thru-vias to the bottom of the die, no additional ground is required. The amplifier is unconditionally stable over all load states (-45 to +85C), and conditionally stable if the input port is open-circuited.

Notes: 1. TAmbient = 22C unless otherwise noted; exceeding any one of these absolute maximum ratings may cause permanent damage to the device 2. Total Power Dissipation is defined as: PTOT = PDC + PIN - POUT where PDC = DC Bias Power, PIN = RF Input Power, POUT = RF Output Power Total Power Dissipation shall be de-rated above 22C as follows: PTOT = (150 - TCASE ) / JC W where TCASE = Temperature of the on the underside of the package or substrate 3. The quoted Thermal Resistance value is a worst-case figure assuming Gold/Tin die attach onto a Copper substrate. The use of epoxy die attach and substrate materials of lower thermal conductivity will increase the Thermal Resistance. Further information and assistance is available on request. 4. JC increases linearly from 175C/W at a TCASE of 22C to 210C/W at a TCASE of 145C

Datasheet v3.0
RECOMMENDED ASSEMBLY SCHEMATIC:
75m nominal gap on each side Input and output thin film substrates with 50 microstrip transmission lines. Substrate thickness 250m or thinner is recommended.
25m dia. Au wire (x2) on input and output ports, less than 1000m length each
Note: The supply de-coupling capacitor (150 pF recommended value) should be placed as close to the MMIC as practical.
150pF capacitor To +VDD
250m Au ribbon recommended
PREFERRED ASSEMBLY INSTRUCTIONS:
GaAs devices are fragile and should be handled with great care. Specially designed collets should be used where possible. The back of the die is metallised and the recommended mounting method is by the use of conductive epoxy following the manufacturer's recommended curing temperature. For eutectic 80/20 gold/tin solder, use a stage temperature of 280-300C for a maximum time of 60s. Use forming gas (90%N2, 10% H2) for best results. Recommended lead bond technique is thermocompression wedge bonding with 25m diameter wire. The bond tool force shall be 35-38g. Bonding stage temperature shall be 230-240C, heated tool (150-160C) is recommended. Ultrasonic bonding is not recommended.
should be observed at all stages of storage, handling, assembly, and testing. These devices should be treated as Class 0 (0-250 V) as defined in JEDEC Standard No. 22-A114. Further information on ESD control measures can be found in MIL-STD-1686 and MILHDBK-263.
