Description
M/A-COM’s MADR-008851-000100 Switch Driver is
designed to work with M/A-COM’s line of series /
shunt SPDT HMIC switches which operate in the
power range of approximately 5 to 20W CW. It is
capable to provide forward bias currents up to 50
mA for each diode in the series/shunt switch, with
back bias voltage configurable from 12V to 32 V. It is
packaged in a Land Grid Array surface mount
package and is available in tape and reel packaging
for high volume applications.
Sample boards are available with M/A-COM 20W
switch MASW-000834-13560T.

Forward Bias Diode Voltage:
Vf
is ~0.9V @ 22 mA;
Vf
is ~1.0V @ 35 mA
R1 is calculated by (VCC -
Vf)
/ I
series
- 22
Ω,
where I
series
is the desired forward bias current for the series diodes. For 20 mA load cur-
rent, R1 = 178
Ω
@ VCC = 5.0V and 93
Ω
@ VCC = 3.3V. For 50 mA load current, R1 = 57.6

@ VCC = 5.0V and 24
Ω
@ VCC=
3.3V.
by I
shunt
x (VDD -
Vf).
For 28V VDD and 20 mA of I
shunt
, R2 should use a 1W, 1.3k ohm resistor.
C8 is already built-in for M/A-COM MASW-000834-13560T switch.
The current through the back-biased diodes will be the leakage current for the diodes
C1-C7, L1-L4, R1, R2, and the switch are discrete components that should be installed on the user’s board. It is recommended that
Coilcraft 0603CS-27NXJLW or equivalent be used for L1-L4 at 2 GHz. For other frequency band, C1-C3 and L1-L4 should be adjusted.
The switching speed will be affected by the value of VCC, VDD, C6, C7, the size of the PIN diodes, and the forward bias currents. Use
higher VCC and VDD, and lower forward bias currents for faster switching.
10. R2 is calculated by (VDD -
Vf)
/ I
shunt
, where I
shunt
is the desired forward bias current for the shunt diode. The power rating is calculated
