Transcription

1 SP4T (Single Pole Four Throw Switch) The RF1119A is a single-pole four-throw (SP4T) switch designed for static Antenna/impedance tuning applications which requires very low insertion loss and high power handling capability with a minimum of DC power consumption. The high linearity performance achieved by the RF1119A make it ideal for use in multi-mode GSM/GPRS/ EDGE/WCDMA/LTE applications. The RF1119A is controlled by a standard GPIO interface for easy control. The RF1119A includes an integrated LDO (Low Drop Out) regulator, which enables operation over a very wide supply range. All pins are ESD protected to ensure 2kV HBM ESD tolerance. The RF1119A is packaged in an ultra-compact 1.6mm x 1.6mm, 11-pin, WLCSP package. RF2 RF1 1 2 RFC 11 RF RF4 RF1119A Package: WLCSP, 11-pin, 1.6mm x 1.6mm Features Low insertion loss: 0.3dB at 1GHz. High peak voltage handling. High linearity. Ultra small package: WLCSP, 11-pin, 1.6mm x 1.6mm. No external DC blocking capacitor required (Unless external DC is applied to the RF ports). Wide VDD voltage range. 2kV HBM ESD protection at all ports.

12 Power ON and OFF sequence It is very important that the user adheres to the correct power-on/off sequence in order to avoid damaging the device. The control signals CTL1 and CTL2 should be set to 0V unless VDD & EN are set in the operating voltage range. RF signal should not be applied on any of the RF ports when the VDD is below 2.4V and the EN is set below VHIGH_EN. Power ON 1) Apply voltage supply - VDD 2) Apply Enable - VEN (VEN can be connected to VDD and applied at the same time) 3) Apply controls - CTL1 and CTL2 4) Wait 20μs or greater and then apply RF Change switch position from one RF port to another 1) Remove RF 2) Change controls CTL1 and CTL2 to set the switch to desired RF port 3) Wait 5μs or greater and then apply RF Power OFF 1) Remove RF 2) Remove controls - CTL1 & CTL2 3) Remove VEN 4) Remove VDD VDD ON VEN ON VCTL set 20µs RF ON RF OFF VCTL set RF ON RF OFF VCTL OFF VEN OFF VDD OFF VDD 0µs 5µs VEN VCTL RF Signal Figure 10 application circuitry and specifications at any time without prior notice. 12 of 13
