Description
M/A-COM Technology Solutions MADR-008888-
000100 Switch Driver is designed to work with M/A-
COM Tech switch MASW-000823-12770T or other series / series switches. This driver is design to pro- vide currents up to 50 mA for each diode in series / series switches. It is designed for SPDT switches that operate with a power range of approximately 5 – 20W CW. The driver is packaged in a Land Grid Array surface mount packa ge and is available in tape and reel packaging for high volume applications. The MADR-008888-000100 driver is ideally suited for driving M/A-COM’s line of HMIC switches. Note that this driver will also operate when VDD is set to voltages other than +28V. It could also oper- ate at +12V, +15V, +20V, and +24V supplies.

Driver and SPDT Schematic with +5V & +28V DC Power 7,8,9,10,11,12,13,14 7. Forward Bias Diode Voltage: Vf is 0.9V @ 22 mA; Vf is 1.0V @ 35 mA 8. For 22 mA load current, R1 = 180 Ω @ VCC = 5.0V and 105 Ω @ VCC = 3.3V. For 35 mA load cur- rent, R1 = 110 Ω @ VCC = 5.0V and 165 Ω @ VCC= 3.3V. Nominal power dissipation in the 180 Ω and 110 Ω resistors are 87 mW and 135 mW. 9. Reverse Bias is ~ 27V (This is the 28V supply minus approximately 1V on the diode). 10. M/A-COM PIN Diode Driver, MADR-008888-0001TR is recommended for usage with the MASW- 000823-12770T SPDT Switch. 11. The voltage at the common anode will be approximately 1.0V. 12. The current in through the back-biased di odes will be the leakage current for the diodes 13. C1-C5, L1-L3, R1, 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-L3 at 2 GHz (values may vary based on the frequency). 14. There are 33 pF bypass capacitors included in the dr iver for the RX and TX ports. There are cases, especially at higher frequencies, where the optional 12 pF bypass capacitors that are shown on the schematic are needed. 100 pF 100VL3 27 nH RX 100 pF 100 pF 100V L2 27 nH Cbypass 12 pF TX ANT SPDT 27 nH 100 pF 100 pF See Note 8 +5V Cbypass 12 pF +5V+28V Ground Logic Input MADR-008888-000100 Switch Driver
