ANTENNAS 3.5 dBi Dipole Patch Antennas The Squint series low profile patch antennas feature a 3.5 dBi dipole-like pattern shape and ceiling-mount capability that provides a low profile for minimum visual impact. The radiation pattern has a 55° beamwidth with the maximum directed at 45° from the horizontal plane....

AMPLIFIERS Masthead Amplifier The model G3 masthead amplifier features a noise figure typically better than 1.4 dB and can increase the receive sensitivity of the base station significantly, eliminating imbalance and improving effective range and quality of coverage. Planning a new GSM1800 or PCS1900 network with the unit could...

DEVICES Schottky Eight-diode Ring Quads The models SMS3938-026, SMS3939-026 and SMS3940-026 low, medium and high barrier eight-diode ring quads, respectively, are designed for use in double-balanced mixers requiring higher compression points and better intermodulation performance than standard four-diode ring quads. The units are packaged in industry-standard SOT-143 packages on...

SOURCES Surface-mount Synthesizers These low cost synthesizers utilize a three-wire serial control interface and exhibit low noise, low spurious levels, low power consumption, fine frequency resolution and small size. Specifications include an output frequency of 500 MHz to 3 GHz with up to 50 percent bandwidths, resolution of 1...

SUBSYSTEMS C-band INTELSAT Synthesizer The LCCB series C-band, low phase noise synthesizer offers a low cost alternative for C-band INTELSAT SATCOM applications. In addition to the 125 kHz step size output at C-band, the synthesizer provides a standard second output at L-band that is used as the second conversion...

MATERIALS EMI Gasket Materials The Cho-Form" series form-in-place EMI gasket materials are developed for automated dispensing systems. The Cho-Form 3.0 series material is a silver-plated, copper-filled silicon with a low 85°C cure temperature; the Cho-Form 4.0 series material is a nickel-graphite-filled silicone formulated to reduce galvanic activity between a...

SYSTEM S-band Airborne Command Control Receiver The model RCC-223-SYN airborne command control receiver is a dual-conversion super-heterodyne UHF unit capable of operating in S-band with a 200 MHz tuning range in 1 MHz steps. The receiver features locally selectable dual IF bandwidths. Tuning is accomplished via remote BCD code...
