The MASW- Pin Configuration 008955 is ideally suited for applications where low control voltage, low insertion loss, high isolation, Pin No. Function Description small size, and low cost are required. 1 RFC RF In/Out 3,4 Typical applications are for filter and antenna 2 V Optional Voltage Pull Up P switching in WLAN or Bluetooth systems that 3 3 V1 Control 1 connect separate receive functions to a common antenna This part can be used in all systems 4 RF1 RF In/Out operating up to 3.5 GHz requiring low control 5 RF2 RF In/Out voltage. 3 6 V2 Control 2 3 The MASW-008955 is fabricated using a 0.5 micron 7 V3 Control 3 gate length GaAs pHEMT process. The process 8 RF3 RF In/Out features full passivation for performance and reliability. 3. Depending on system sensitivity optional DC line bypass capacitors (22 pF) may be used. 4. Improved linearity at low control voltage can be obtained by tying pin 2 to the most positive control voltage. Otherwise, leave pin 2 unconnected. 1,2 Ordering Information 5,6 Absolute Maximum Ratings Part Number Package Parameter Absolute Maximum MASW-008955-TR1000 1000 piece reel Max Input Power (0.5-3.5 GHz, 2.6 V Control) MASW-008955-TR3000 3000 piece reel RFC RF1 35 dBm RFC RF2 31 dBm MASW-008955-001SMB Sample Test Board RFC RF3 31 dBm 1.

For positive control voltage, external DC blocking capacitors are required on all RF ports. 8. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 100 pF for 100 - 500 MHz, 39 pF for 2.45 GHz. 9. Specifications apply with no connection to pin 2 (V ).
