Description
was developed for shunt mount applications in
microstrip circuits. Good switch performance
is demonstrated at frequencies from UHF to 4
GHz and higher. This performance is achieved
using discrete low inductance Microsemi PIN
diodes assembled with special hardware to
permit good electrical and mechanical
compatibility with microstrip transmission
lines.
preparation of microstrip circuit boards to
accommodate these PIN diodes. A detailed
design for a 900 MHz quarter-wave antenna
switch is given. This switch which employs a
low cost UM9401 axial leaded PIN diode in
conjunction with a UM9601 performs with 30
dB receiver isolation over a 100 MHz
bandwidth and with a transmitter insertion
loss of less than 0.4 dB. This switch can safely
handle transmitter power levels up to 100
watts at infinite SWR.

constructed using a fused-in-glass which results in
a highly reliable, hermetic package. The process
utilizes symmetrical, full faced metallurgical
bonds to both surfaces of the silicon chip. This
construction greatly minimizes the normal
parasitic inductance and capacitance found in
conventional glass or ceramic packaged diodes
which employ straps, springs, or whiskers.
greatly minimizes handling problems commonly
associated with passivated PIN diode chips while
maintaining good microwave performance. In
addition the power handling capability of the
UM9601-UM9608 series is considerably higher
than PIN diode chips can provide.
