AWS5508 SP4T PHEMT Transmit/Receive Antenna Switch GSM 900 MHz/DCS 1800 MHz/PCS 1900 MHz ADVANCED PRODUCT INFORMATION - Rev 0.3 FEATURES • • • • 2.7V Control Operation Tri-band Operation High Isolation High Power • • High Linearity Small Leadless Package APPLICATIONS • SP4T Antenna switch operating in the GSM 900 MHz, DCS 1800 MHz, and PCS 1900 MHz bands PRODUCT DESCRIPTION S19 MLP-16 Multipin Leadless Plastic Package The AWS5508 SP4T high power antenna switch is designed to operate in the GSM 900Mhz, DCS 1800MHz, and PCS 1900MHz frequency bands. All 4 ports of the switch have identical electrical and linearity performance which allows flexibility in system design. Switching between ports is accomplished using 2.7 to 6 volts differential control voltages on the 4 control pins. The switch is provided in a leadless MLP-16 quad flat package. RFc Optional Rs Note 3 Cb Vs V4 GND PIN 1 INDICATOR 1. DC blocking capacitors Cb and optional resistor Rs must be supplied externally. 2. Cb = 100 pF for operation >500MHz. 3. The use of resistor Rs to the positive voltage supply is optional. It is only required if it is necessary to have all RF ports in Isolation state at the same time. Also, using Rs will improve linearity performance to a small degree when VCTL is at its lower limit. Rs = 10k Ω when used.

AWS5508 ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT - 8 W Control Voltage -0.4 10 V Operating Temperature -40 +125 °C Storage Temperature -65 +150 °C RF Input Power > 500 MHz, VCTL = 2.7V 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. Control Voltage is the diffenterial voltage between any of pins V1, V2, V3, V4 and RFc.

Notes: 1. All measurements made in a broadband 50 Ω system. 2. Video feedthru measured with 1 ns risetime pulse and 500MHz bandwidth. 3. VCTL is the differential voltage between any one of the control pins (V1 through V4) and the remaining three control pins. Changing which control pin is the most positive voltage 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 ± 0.2V. 2 ADVANCED PRODUCT INFORMATION - Rev 0.3 08/2001 AWS5508 Table 4: Electrical Specifications at 25 °C (VCTL = 2.7V) PARAMETER CONDITION FREQUENCY Insertion Loss PIN = +34dBm 0.5 - 1.0 GHz 1.0 - 2.0 GHz Isolation PIN = +34dBm 0.5 - 1.0 GHz 1.0 - 2.0 GHz VSWR In Low Loss Path 0.5 - 2.0 GHz MIN 22 18 TYP MAX UNIT 0.65 0.90 0.8 1.0 dB dB 25 21 dB dB 1.20:1 1.35:1 Table 5: Harmonics HARMONIC LEVEL (DBC) TYP.
