General Description
The HMC197 is a low-cost SPDT switch in a 6lead SOT26 plastic package for use in general
switching applications which require very low
insertion loss and very small size. The device
can control signals from DC to 3.0 GHz and is
especially suited for 900 MHz, 1.8-2.2GHz, and
2.4GHz ISM applications with less than 1dB
loss. The design provides exceptional insertion
loss performance, ideal for filter and receiver
switching. RF1 or RF2 is a reflective short when
"Off". The two control voltages require a minimal
amount of DC current and offer compatibility
with most CMOS & TTL logic families. The
HMC197 is especially suited for PCMCIA wireless card and cellular phone applications. See
HMC221 for same performance in an alternate
SOT26 pin-out.
Guaranteed Performance Vctl = 0/+3 to +8 Vdc, -40 to +85 deg C
