Description
The HPND-4028 and 4038 beam
lead PIN diodes are designed for
low capacitance, low resistance,
and fast switching at microwave

DIMENSIONS IN µM (1/1000 INCH)
frequencies. These characteristics
are achieved at low bias levels for
minimal power consumption.
Advanced processing techniques
ensure uniform and consistent
electrical performance, allowing
guaranteed capacitance windows.
This translates to improved
performance in phased array
applications.

Applications
Rugged construction and strong
beams ensure high assembly
yields while nitride passivation
and polyimide coating ensure
reliability.
array radar. The low capacitance
makes them ideal for circuits
requiring high isolation in the
series configuration. These
devices have been fully charac-
terized and S-parameters have
been provided.
These beam lead PIN diodes are
designed for use in stripline,
coplanar waveguide, or micro-
strip circuits. Applications
include phase shifting and
switching. The guaranteed
capacitance windows ensure
uniform performance in phased
