ANTENNA ISM-band Single-patch Antenna The model S9029P industrial, scientific and medical (ISM)-band antenna provides reception and transmission of linearly polarized signals in the 902 to 928 MHz frequency band. It features etched copper circuitry, which improves data transmission. The antenna consists of a single broadband microstrip patch that provides...

AMPLIFIERS 200 W Class AB Power Amplifier The model 30-2-200-45 200 W class AB power amplifier operates from 1 to 30 MHz and is housed in a compact package (6" x 2" x 1") or as a full 19" rack-mount system. Module connectors are SMA female and rack-mount connectors...

DEVICES Tunnel Diode Detector Assemblies The DTN2040 series microwave detector assemblies are designed with tunnel diodes that provide temperature stability without any bias requirement. Tangential sensitivity is typically –52 dBm with a voltage sensitivity of 1000 mV/mW over a 2 to 4 GHz frequency bandwidth. The detectors can be...

INTEGRATED CIRCUITS DECT RF Chipset This RF chipset designed for use in Digital European Cordless Telephone (DECT) applications uses SiGe technology and a closed-loop modulation concept to prevent undesired frequency deviations, resulting in less expenditure of shielding, better performance and faster production time. The RF chipset is offered as...

SOURCES High Frequency VCO The model VCO691-5800T high frequency VCO features a frequency range from 5700 to 5900 MHz, supply voltage of +3 V and phase noise of –99 dBc/Hz (typ) at 100 kHz offset. Typical output power is –7 dBm. Second and third harmonics are –15 dBc (typ)...

TEST EQUIPMENT Radar Return Simulator Assembly The model 1663 radar return simulator assembly operates in Ku-band and is designed to provide a programmable phase and amplitude relationship between two channels for simulating radar return signals. The module interfaces with a waveguide manifold, which in turn interfaces with the waveguide...

PROCESSING EQUIPMENT PCB Prototyping System The ProtoMat 91s/HS PCB prototyping system produces PCBs with trace edges and holes that are within 0.02 mils (5 mm) of design position. Tool change is quicker and easier with the incorporation of a lever tool release and a collect mechanism. These features allow...
