Description and Applications
M/A-COM's MA4E1317 single, MA4E1318 anti-parallel
pair, MA4E1319-1 reverse tee and MA4E1319-2
series tee are gallium arsenide flip chip Schottky
barrier diodes. These devices are fabricated on
OMCVD epitaxial wafers using a process designed
for high device uniformity and extremely low
parasitics. The diodes are fully passivated with
silicon nitride and have an additional layer of
polyimide for scratch protection. The protective
coatings prevent damage to the junction during
MA4E1318
automated or manual handling.
The flip chip
configuration is suitable for pick and place insertion.
The high cutoff frequency of these diodes allows use
through millimeter wave frequencies. Typical applications
include single and double balanced mixers in PCN
transceivers and radios, police radar detectors, and
automotive radar detectors. The devices can be
used through 80 GHz.
MA4E1319-1
The MA4E1318 anti-parallel pair is designed for use
in subharmonically pumped mixers. Close matching
of the diode characteristics results in high LO
suppression at the RF input.

Notes:
1. Total capacitance is equivalent to the sum of junction capacitance Cj and parasitic capacitance Cp.
2. Series resistance is determined by measuring the dynamic resistance and subtracting the junction resistance of 2.6 ohms.
3. Capacitance for the MA4E1318 and MA4E1319-1 or -2 is per Schottky diode.
4. Measured at an LO frequency of 9.375 Ghz, with an IF frequency of 300 Mhz. LO drive level is +6 dBM for a single Schottky junction. The
IF noise figure contribution (1.5 dB) is included.

Mounting Techniques
Handling
These chips were designed to be inserted onto hard
or soft substrates with the junction side down. They
can be mounted with conductive epoxy or with a low
temperature solder preform. The die can also be
assembled with the junction side up, and wire or
ribbon bonds made to the pads.
The following precautions should be observed to
avoid damaging these chips:
Cleanliness: These chips should be handled in a
clean environment. Do not attempt to clean die after
installation.
Static Sensitivity: Schottky barrier diodes are ESD
sensitive and can be damaged by static electricity.
Proper ESD techniques should be used when
handling these devices.
Solder Die Attach: Solders with < 30% Sn by volume
or weight are recommended. 80 Au / 20 Sn and
Indalloy #2 solders are recommended. Do not
expose die to a temperature greater than 235°C, or
greater than 200°C for longer than 10 seconds. No
more than three seconds of scrubbing should be
required for attachment.
General Handling: The protective polymer coating
on the active areas of these die provides scratch
protection, particularly for the metal airbridge which
contacts the anode. Die can be handled with
tweezers or vacuum pickups and are suitable for use
with automatic pick-and-place equipment.
Conductive epoxy Die Attach: Assembly can be
preheated to 125 - 150°C. Use a controlled amount
of epoxy approximately 2 mils thick. Cure epoxy as
per manufacturer’s schedule. For extended cure
times, temperatures should be kept below 200°C.
