RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Hittite Press Release - November 3, 2011
Hittite's New Ceramic Packaged GaAs MMIC SPDT Switch Spans DC to 28 GHz
-- Non-Reflective Switch Offers High Isolation and Low Insertion Loss
Chelmsford, MA, 11/03/2011 – Hittite Microwave Corporation, the world class supplier of complete MMIC based
solutions for communication & military markets, announces the release of a new ceramic packaged, GaAs pHEMT MMIC
Single Pole Double Throw (SPDT) Switch which is ideal for microwave radio, wideband telecom, electronic warfare
(EW), industrial sensors, and test equipment applications from DC to 28 GHz.
HMC547LC3 is a wideband,
high isolation GaAs pHEMT MMIC SPDT switch which provides 40 dB isolation and less than 2 dB insertion loss at
HMC547LC3 is controlled by
two complementary logic inputs of -5/0V, and requires no DC bias supply. High input IP3 of +46 dBm and fast
switching speed of 6 ns allow this switch to be used in numerous locations in advanced military and millimeterwave
transceivers and subsystems.
HMC547LC3 DC to 28 GHz SPDT
Switch MMIC is housed in a ceramic 3 x 3 mm leadless surface mount package, and complements Hittite's broad line
of single, double and multi-throw switches with frequency coverage to 86 GHz. For applications which require
slightly less operating bandwidth, this same SPDT MMIC switch is also available in a 3 x 3 mm plastic QFN leadless
package as the
HMC547LP3E, and operates
from DC to 20 GHz.
Samples of all SMT packaged products are available from stock and can be ordered via the
company's e-commerce site or via direct purchase order. Released data sheets are available on-line at
