biased microstrip circuits in which a UM9601 diode was
installed. Each circuit consisted of a 1 inch length of 50 Ohm
nominal impedance 0.025” (.635mm) thick alumina microstrip
and two SMA connectors. The data shown include the board
and connector loss. Measurements performed using 00.050”
(1.27mm) alumina substrates show similar performance at
frequencies to1.5 GHz

FOR MICROSTRIP 900 MHz ANTENNNA SWITCHES
require multi-throw switches. It is important to recognize that a
multi-throw switch will have 6dB higher isolation than
indicated for SPST switches. Also, a multi-throw switch using
shunt mounted PIN diodes require the diodes be placed a
quarter-wavelength from the common port.
achieved by using 2 shunt PIN diodes in each arm spaced a
quarter-wavelength from each other. In this case the isolation of
each section will be twice the dB value of the switch. The
insertion loss due to the diodes should be less than twice the
insertion loss of an SPST section due to the transforming effect
of the quarter-wave line on the capacitance of a single diode.
