Applications

This line of Schottky diodes is

optimized for use in mixer

applications at millimeter wave

frequencies. Some suggested

mixer types are single ended and

single balanced for the single and

series pair. The anti-parallel pair

is ideal for harmonic mixers.

Assembly Techniques

Diodes are ESD sensitive. ESD

preventive measures must be em

ployed in all aspects of storage,

handling, and assembly.

Diode ESD precautions, handling

considerations, and bonding

methods are critical factors in

successful diode performance

and reliability.

Agilent application note #55,

“Beam Lead Diode Bonding and

Handling Procedures” provides

basic information on these

subjects.

Notes:

1. Junction capacitance is determined by measuring total device capacitance and subtracting the calculated parasitic capacitance (0.035 pF).

2. Series resistance is determined by measuring the dynamic resistance and subtracting the calculated junction resistance of 6

Ω.
