Typical Applications

The HMC1055LP2CE is ideal for:

• RFID & Electronic Toll Collection (ETC)

• Tags, Handsets & Portables

• ISM, WLAN, WiMAX & WiBro

• Automotive Telematics

• Test Equipment

The HMC1055LP2CE is low-cost SPST Failsafe

switch in 2x2mm,8 lead DFN plastic package for

use in switching application which require low

insertion loss and very low current consumption.

With 0.7 dB typical loss, these devices can control

signals from DC to 4 GHz and are especially suited

for IF and RF applications including RFID, ISM,

automotive and battery powered tags and portables.

RF1 and is reflective open while RF2 is terminated in

50 OHMs when “Off”. The switch requires a minimal

amount of DC current in the “On” state, and offers

compatibility with CMOS and some TTL logic families.

The failsafe topology results in the switch being

normally “On”, i.e. low insertion loss from RF1 to RF2,

when no DC bias is applied.
