HMICTM Silicon PIN Diode SPDT Switch

50 MHz - 20 GHz

Rev. V7

Bias Control

Driver Connections

Optimal operation of the MASW-002103-1363 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 arm 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.

7. As long as 20mA is applied through the on diodes, the voltage can

vary.

Example:

J1 to J2→ Low Loss

R1 = 250Ω

R2 = 450Ω

B2 = -15V

B3 = 6V

Application Circuit 8,9,10,11,12

Notes:

8. Assume Vf ~ 1V at 20mA

9. R1 = 5V / 0.02A = 250Ω; R2 = 9V / 0.02A = 450Ω

10. PR1 = 0.02A x 0.02A x 250 = 0.1 W

11. PR2 = 0.02A x 0.02A x 450 = 0.18 W

12. Inductors are bias RF chokes. The operating band width of a broad-band PIN diode switch is often dependent on the bias compo-

nents, particularly the RF bias chokes. It is suggested that the frequency response be checked with all the bias components attached

before installing the PIN diode.
