The switch handles greater than 20 W of CW power over the 8.0 - 10.5 GHz frequency band. 2 The device is fabricated using MACOMs patented Pin Configuration HMIC process, which allows for the integration of silicon pedestals that embed series and shunt diodes in Pin Function low loss, low dispersion glass. The switch offers low insertion loss of 0.8 dB as well as high isolation J1 RF COMMON performance of 37 dB. The device integrates a bias network to allow for simplified bias application and J2 RF OUT switch control. J3 RF OUT The topside is fully encapsulated with silicon nitride passivation and an additional polymer layer for scratch B2 Bias of J2 and impact protection. These protective coatings prevent damage to the semiconductor junctions and B3 Bias of J3 metal air bridges during handling and assembly. 2. The exposed metallization on the chip bottom must be connected to RF, DC and thermal ground. 1 Ordering Information Part Number Package MASW-010647-13950G Die in Gel Pack MASW-010647-13950W Die in Waffle Pack 1.

R. Caverly and G. Hiller, Establishing the Minimum Reverse Bias for a P-I-N Diode in a High Power Switch, IEEE Transactions on Microwave Theory and Techniques, Vol.38, No.12, December 1990 4. Typical switching speed measured from 10% to 90 % of detected RF signal driven by TTL compatible drivers. MACOM recommends the MADR-007097, Complementary Channel TTL PIN Diode Driver. 3 Driver Connections Bias Control Optimal operation is achieved by simultaneous DC Control Voltages Condition of application of negative DC voltage to the low loss (DC Currents) RF Output switch path and positive DC voltage to the isolating B2 B3 J1-J2 J1-J3 switch path. 3 -5 V +5 V In the low loss path, the diodes are reverse biased. Low Loss Isolation (0 mA) (55 mA typ.) In the isolating path, the diodes are forward biased. 3 +5 V -5 V Isolation Low Loss Minimum Reverse Bias Required: (55 mA typ.) (0 mA) At X-Band, with a 1:1 match, 5 V of reverse bias is required. With a 4:1 match, 10 V of reverse bias is required. However MACOM recommends 30 V of reverse bias to achieve optimal operating conditions. 22 2 M/A-COM Technology Solutions Inc.
