High Linearity Broadband SP2T 5MHz to 10GHz F2972 Datasheet © 2017 Integrated Device Technology, Inc. 1 Rev O April 19, 2017

Description

The F2972 is a singleMpole doubleMthrow (SP2T) reflective RF switch featuring high linearity and wide bandwidth. This device is optimized from 5MHz to 1.8GHz to support downstream cable modem future migration for DOCSIS 3.1 applications, and operates at up to 10GHz to support a multitude of wireless RF applications. Superb performance is achieved when used in either 50Ω or 75Ω terminating impedance applications. The F2972 uses a single positive supply voltage of either +3.3V or +5.0V and is compatible with either 1.8V or 3.3V control logic. Competitive Advantage The F2972 provides extremely low insertion loss across the entire bandwidth while providing superb distortion performance. /square4 Optimized for DOCSIS 3.1 applications up to 1.8GHz /square4 Optimized for WiMFi applications up to 5.9GHz /square4 Low insertion loss /square4 High isolation /square4 Fast switching /square4 No external matching required Typical Applications /square4 Broadband cable DOCSIS 3.0 / 3.1 /square4 Set top box /square4 CATV filter bank switching /square4 WiMFi /square4 Cellular BTS /square4 General purpose General Features /square4 Supply voltage: +2.5V to +5.25V /square4 1.8V and 3.3V compatible control logic /square4 2mm x 2mm, 12Mpin TQFN package Features (75Ω) /square4 Low insertion loss: /square40.23dB at 204MHz /square40.34dB at 1.8GHz /square4 High Isolation: 40dB at 1.8GHz /square4 P0.1dB compression of +37dBm at 204MHz /square4 Second Harmonic: M100dBc at 204MHz /square4 Third Harmonic: M120dBc at 204MHz /square4 Composite Second Order Distortion > 100dBc /square4 Composite Triple Beat Distortion > 100dBc Features (50Ω) /square4 Low insertion loss: /square40.40dB at 2.4GHz /square40.55dB at 8GHz /square4 High Isolation: /square434dB at 2.4GHz /square4 High Linearity: /square4IIP2 +125dBm at 2.4GHz /square4IIP3 +77dBm at 2.4GHz /square4 P0.1dB compression of +40dBm at 2.4GHz /square4 Second Harmonic: M100dBc at 2.4GHz /square4 Third Harmonic: M110dBc at 2.4GHz Block Diagram Figure 1.

Application Information

A common VCC power supply should be used for all pins requiring DC power. All supply pins should be bypassed with external capacitors to minimize noise and fast transients. Supply noise can degrade noise figure and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or transients should have a slew rate smaller than 1V / 20µs. In addition, all control pins should remain at 0V (+/M0.3V) while the supply voltage ramps up or while it returns to zero. Control Pin Interface If control signal integrity is a concern and clean signals cannot be guaranteed due to overshoot, undershoot, ringing, etc., the following circuit at the input of each control pin is recommended. This applies to control pins 7 and 8 as shown below. Figure 26. Control Pin Interface Schematic

For the 758glyphV3V EVKit, connect the disabled Vcc supply connection to J6 pin 2 and GND to J6 pins 1 or 5. For the 508glyphV3V EVKit, connect the disabled Vcc supply connection to J6 pin 3 and GND to J6 pin 1, 2, 4, 6, 8, 9, or 10. Logic Control Setup With the logic control lines disabled set the HIGH and LOW logic levels to satisfy the levels stated in the electrical specifications table. For the 758glyphV3V EVKit, connect the disabled logic control lines to J6 EN (pin 3) and V CTL (pin 4). For the 508glyphV3V EVKit, connect the disabled logic control lines to J6 EN / LS (pin 5) and VCTL (pin 7). See Table 9 for the logic truth table. Turn On Procedure Setup the supplies and EVKit as noted in the External Supply Setup and Logic Control Setup sections above. Enable the V CC supply. Enable the logic control signals. Set the logic setting to achieve the desired Table 9 configuration. Note that external control logic should not be applied without V CC being present. Turn Off Procedure Set the logic control pins to a logic LOW. Disable the V CC supply.
