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...

Anatech Electronics Intros New BPFs & Couplers
REVISIT OUR PRODUCTS FOR WIRELESS & DEFENSE! Haven't looked over out broad
range of cavity, ceramic, LC, and SAW filters, duplexers, triplexers, and multiband combiners
recently? If you do, you'll find new models and a greater range of models than ever before.
907.5 MHz Cavity Bandpass Filter
The AB907B781 cavity bandpass
filter is designed for outdoor applications and has a center frequency of 907.5 MHz, 1.5-dB
bandwidth of 905 to 910 MHz, insertion loss of 3 dB or less, and out-of-band rejection of
at least 75 dB from 850 to 889 MHz and 919 to 950 MHz. It has a maximum RF power handling
of 20 W CW, passband ripple of 0.2 dB or less, return loss of at least 15 dB, and an operating
temperature range of -40 to +75o C. The filter is housed in a 140 x 80 x 53 mm enclosure
and uses Type-N female connectors.
5725 MHz Ceramic Bandpass Filter
The AM5725B1162 ceramic bandpass filter has a center frequency of 5725 MHz,
a 1-dB bandwidth of 90 MHz (5680 to 5770 MHz), insertion loss of 5 dB or less, passband
ripple of 1.2 dB or less, return loss of at least 12 dB, and rejection of at least 30 dB
at 5525 MHz and 5925 MHz. The filter is housed in a 1.04 X 0.44 X 0.23 in. package and has
an operating temperature range of -30o to +70o C.
800 to 2170 MHz 30-dB Dual Directional Coupler
30-dB dual-directional coupler operates from 800 to 2170 MHz, handles 500 W average and
3 kW peak RF power input, and is well suited for base station RF power monitoring. It has
very low third-order intermodulation distortion of -155 dBc, insertion loss of 0.5 dB, coupling
flatness of 0.75 dB, directivity of at least 25 dB, and VSWR of 1.07:1. The coupler measures
6.25 x 1.72 x 1.72 in. and uses 7-16 DIN connectors in the main line and Type-N female connectors
at the coupled port. Models with custom connectors and enhanced directivity are available.
