AWS5508 SP4T PHEMT Transmit/Receive Antenna Switch GSM 900 MHz/DCS 1800 MHz/PCS 1900 MHz FEATURES • • • • • • • 2.7V Control Operation Tri-band Operation High Isolation High Power High Linearity Small Leadless Package SP4T Antenna switch operating in the GSM 900 MHz, DCS 1800 MHz, and PCS 1900 MHz bands ADVANCED PRODUCT INFORMA TION - Rev 0.3 APPLICATIONS PRODUCT DESCRIPTION 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. 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.

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 INFORMA TION - Rev 0.3 08/2001 AWS5508 Table 4: Electrical Specifications at 25 °C (VCTL = 2.7V) PARAMETER Insertion Loss Isolation VSWR CONDITION PIN = +34dBm PIN = +34dBm In Low Loss Path FREQUENCY 0.5 - 1.0 GHz 1.0 - 2.0 GHz 0.5 - 1.0 GHz 1.0 - 2.0 GHz 0.5 - 2.0 GHz MIN TYP 0.65 0.90 MAX 0.8 1.0 UNIT dB dB dB dB 22 18 25 21 1.20:1 1.35:1 Table 5: Harmonics HARMONIC LEVEL (DBC) TYP.
