Low Series Resistance
Low Capacitance
High Cut-Off Frequency
Silicon Nitride Passivation
Multiple Configurations
Description and Applications
The MA4E2037 and MA4E2038 single diodes,
MA4E2039 anti-parallel pair and MA4E2040 series
tee are gallium arsenide beam lead Schottky barrier
diodes. These devices are fabricated on OMCVD
epitaxial wafers using a process designed for high
device uniformity and extremely low parasitics. The
high carrier mobility of gallium arsenide results in
lower series resistance than a silicon Schottky with
equivalent capacitance, resulting in lower noise
figure and conversion loss. The diodes are fully
passivated with silicon nitride and have an additional
layer of a polymer for scratch protection. The
protective coatings prevent damage to the junction
and the anode air bridge during handling.
MA4E2039
The high cut-off frequency of these diodes allows
use through millimeter wave frequencies. Typical
applications include single and double balanced
mixers in PCN transceivers and radios, automotive
radar systems and police radar detectors.
The MA4E2039 anti-parallel pair is designed for use
in sub harmonically pumped mixers. Close matching
of the diode characteristics in high LO suppression
at the RF input.

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 MA4E2039 and MA4E2040 is per Schottky diode.

Handling Procedures
4. Exceeding any one or combination of these limits may cause
permanent damage to this device.
The protective polymer coating on the active areas
of these die provides scratch protection, particularly
for the metal air bridge which contacts the anode.
Beam lead devices must, however, must be
handled with care since the leads may be easily
distorted or broken by the normal pressures
exerted when handled by tweezers. A vacuum
pencil with a # 27 tip is recommended for picking
and placing.
5. MACOM does not recommend sustained operation near these
survivability limits.
