4220 overview

4220 is a component documented by Peregrine Semiconductor. The PDF description identifies it as "SPDT UltraCMOS??RF Switch DC - 2500 MHz." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Datasheet snapshot

  • Manufacturer: Peregrine Semiconductor...

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • Device linearity will begin to degrade below 10 MHz.
  • The DC transient at the output of any port of the switch when the control voltage is switched from Low to High or High to Low in a 50Ω test set-up, measured with 1ns risetime pulses and 500 MHz bandwidth. **Table 1.
  • Electrical Specifications @ +25 °C, VDD = 3 V (ZS = ZL = 50 Ω) Figure 2.
  • Nominal 3 V supply connection.
  • A bypass capacitor (100 pF) to the ground plane should be placed as close as possible to the pin CTRL CMOS or TTL logic level: High = RFC to RF1 signal path Low = RFC to RF2 signal path GND Ground connection.

Topics covered by the datasheet

  • Description

Engineering review checklist

  • Verify capacitance tolerance, rated voltage, temperature range and any DC-bias derating.
  • Check ESR, ripple-current capability, lifetime and polarity requirements under worst-case conditions.
  • Confirm package dimensions, land pattern and reflow or mounting limits for the selected ordering code.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
