HMICTM Silicon PIN Diode SP3T Switch

Rev. V2

Bias Control

Optimal operation of the MASW-003103-1364 is achieved by simultaneous application of negative DC voltage

and current to the low loss switching arm J2, J3, or J4, 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 J1/RF Com 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 isolation arms, the shunt diode is forward biased with current and the series diode is reverse

biased with voltage.

7. The voltage applied to the off arm can vary as long as 20mA is applied through the shunt diode on the off arm.

Application Circuit 8,9,10,11,12

Example:

J1 to J2→ Low Loss

R1 = 250Ω

R2 = 450Ω

B2 = -15V

B3, B4 = 6V

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
