HaRP™-enhanced switch has best-in-class linearity, making it ideal for use in test and measurement applications including Automated Test
Equipment (ATE) and general-purpose test and
measurement; RF/IF transceiver signal switching;
filter bank switching; and discrete DSA stages.

test system for 3G mobile phones self-contained. Previously, tests were controlled through
test scripts running on a PC utilizing the company’s 7310 Lector and Scriptor remote control
software. With the new option, the test scripts
can reside on the instrument itself and a comprehensive test system for service can be reduced to the company’s 2201 ProLock with the

Absorptive Switch Matrix
AKON Inc.’s switches and filters division
developed a 36-throw absorptive switch matrix
measuring 7. 3" × 5. 4" × 1.2". The model A35-
WH183 operates over the 0.3 to 3. 3 GHz frequency range, with less than 10 dB insertion
loss, less than 0.8 d B peak-to-peak v a r i a t i o n b e - tween the J0 in- put port and any output port, less than four de- grees phase variation, 70 nanoseconds or less switching speed, and
+ 30 dBm maximum operating import power. The
unit is ideal for airborne EW/ECM applications.

Ceramic Bandpass Duplexer
The AM1880-1960D268 surface-mount mono-block ceramic duplexer is an excellent choice
for use in base station transceivers serving wireless communication applications. The duplexer’s center frequency is 1920 MHz and transmit
band (1850 to 1910 MHz) insertion loss is less
than 3. 4 dB. Re- turn loss is at least 11 dB, and rejection is at least 49 dB. In- sertion loss in the receive band (1930 to 1990
MHz) is less than 3. 7 dB, return loss is greater
than 11 dB, and rejection is at least 54. 5 dB.
The 50 ohm duplexer will handle RF input
power of 2 W and measures 4. 6 × 23 × 6. 5 mm.

The compact and easy to use IMK Series re- sistive couplers function well over a DC to 15 GHz range. In- sertion loss is
comparable to the more complicated frequency
sensitive couplers. This 0.120" × 0.120" device
is available with a coupling range from 6 to 30
dB and is rated at 1 W. Samples of the IMK Series resistive coupler are available.

Newvaluesfor theDNrangeof tappersare availablefor outdoorandin- buildingdistrib- utedantenna systemapplica-tions, where tappers can replace directional
couplers at far lower cost and improved performance. The new 20 and 30 dB tappers add to
the range of taps that starts at just 3 dB, a 2:1
split. All have much improved VSWR over previous tapper designs and are 50 percent lower in
price than the equivalent directional coupler.
Each has a bandwidth covering all of the wireless bands from 380 to 2700 MHz, thus including Tetra, SMR/PMR and all cellular bands, including the new 700 MHz and WiMAX 2500
MHz band. Also important, the guaranteed Passive Intermodulation (PIM) performance of all
models is <- 150 dBc.
