The AWS5518 is designed for applications that require low insertion loss, high isolation, high linearity, and small size. The switch can be controlled with positive, negative, or a combination of both voltages.

DC blocking capacitors C1,2,3 and optional resistor Rs must be supplied externally. 2. C1,2,3 = 100 pF for operation >500 MHz. 3. The use of resistor Rs to the positive voltage supply is optional. It is only required if it is necessary to independently control the RF ports, such as selecting both ports to be OFF at the same time. 03-2002 AWS5518 ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT - 6 W Control Voltage -0.2 +8 V Operating Temperature -40° +85 °C Storage Temperature -65 +150 °C - 25° C/W RF Input Power > 900 MHz, V Control θJC Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability.

Notes: 1. All measurements made in a 50 Ohm system, unless other specified. (2) Video feedthru measured with 1 ns rise time pulse and 500 MHz bandwidth. (3) VCTL is the absolute value of the differential voltage from V1 to V2. Changing polarity selects the switch path as defined in the truth table below. Use of the optional resistor Rs on the common port limits VHIGH to Vs ±0.2 V. 2 PRELIMINARY DATA SHEET - Rev 1.0 03/2002 AWS5518 Table 4: Electrical Specifications at 25 °C (VCTL = 2.7 V) PARAMETER Insertion Loss FREQUENCY (2) (1) MIN DC - 1.0 GHz DC - 2.0 GHz (3) Isolation DC - 1.0 GHz DC - 2.0 GHz VSWR(3) 0.5 - 2.0 GHz 25 22 TYP MAX UNIT 0.35 0.45 0.45 0.55 dB 32 24 dB 1.4:1 dB Notes: (1) All measurements made in a 50 Ω system, unless other specified.
