series and shunt connected PIN diodes. This device
is designed for use in broadband, low to moderate
signal, high performance, switch applications up to
20 GHz. It is a surface mountable switch configured
for optimized performance and offers a distinct
advantage over MMIC, beamlead and chip and wire
hybrid designs. Because the PIN diodes of the
MASW-004103-1365 are integrated into the chip
and kept within close proximity, the parasitics
typically associated with other designs that use
individual components are kept to a minimum.
To minimize the parasitics and achieve high
performance the MASW-004103-1365 is fabricated
using MACOMs’ patented HMIC™ (Heterolithic
Microwave Integrated Circuit) process. This process
allows the silicon pedestals, which form the series
and shunt diodes or vias, to be imbeded in low loss,
low dispersion glass. The combination of low loss
glass and using tight spacing between elements
results in an HMIC device with low loss and high
isolation through low millimeter wave frequencies.
The topside is fully encapsulated with silicon nitride
and also has an additional layer of polymer for
scratch and impact protection. The protective
coating guards against damage to the junction and
the anode airbridges during handling and assembly.
On the backside of the chip gold metalized pads
have been added to produce a solderable surmount
device.

MASW-004103-1365
Silicon SP4T Surface Mount HMIC PIN Diode Switch
50 MHZ - 20 GHz
Bias Control
Optimal operation of the MASW-004103-1365 is achieved by simultaneous application of negative DC voltage
and current to the low loss switching arm and positive DC voltage and current to the remaining switching arms
as shown in the applications circuit below. DC return is achieved via R2 on the RFC path. In the low loss state,
the series diode must be forward biased with current and the shunt diode reverse biased with voltage. In the
isolated arm, the shunt diode is forward biased with current and the series diode is reverse biased with voltage.

Inductors shown in the above schematic are RF bias chokes. The operating bandwidth of a broad-band PIN diode switch is often
dependent on the bias components, particularly the RF bias chokes. It is suggested that the response at the frequencies of interest be
measured with all the bias components in place prior to installing of MASW-004103-1365.
