Description
The MASW-004100-1193 is a SP4T, series-shunt,
broad band, PIN diode, switch made with M/A-COM
Tech’s unique HMIC
TM
(Heterolithic Microwave
Integrated Circuit) process, US Patent 5,268,310.
This process allows for the incorporation of silicon
pedestals that form the series and shunt diodes or
vias by imbedding them in a low loss, low dispersion
glass. This hybrid combination of silicon and glass
gives HMIC switches exceptional low loss and
remarkable high isolation through low millimeter-
wave frequencies.

Applications
This high performance switch is suitable for use in
multi-band ECM, radar, and instrumentation control
circuits where high isolation to insertion loss ratios
are required. With a standard +5V/-5V, TTL
controlled PIN diode driver, 50nS switching speeds
are achieved.

Typical switching speed is measured from 10% to 90% of detected RF voltage driven by a TTL compatible driver. Driver
output parallel RC network uses a capacitor between 390pF – 560pF and a resistor between 150Ω – 220Ω to achieve 50nS
rise and fall times.

Operation of the MASW-004100-1193 Switch
The simultaneous application of negative DC current to the low loss port and positive DC current to the
remaining isolated ports as shown in Figure 1 will operate the MASW-004100-1193 PIN diode switch. The
backside metalized area of the die is the RF and DC return ground plane. The DC return is achieved on
common Port J1. A current source should be used to supply the DC control currents. The voltages at
these points will not exceed ±1.5 volts and are typically 1.2 volts for supply currents up to ± 20 mA. For
the port in low loss state, the series diode must be forward biased and the shunt diode reverse biased.
For all the isolated ports, the shunt diode is forward biased and the series diode is reverse biased. A
typical bias network design which should provide >30 dB RF to DC isolation is shown in Figure 1.
Best
insertion loss, P1dB, IP3, and switching speed are achieved by using a voltage pull-up resistor in the
DC return path, J1 (not shown). A minimum value of |-2V| is recommended at this return node and
can be obtained using a standard, 65V, TTL controlled, PIN diode driver.
