RFMW Ltd. announces design and sales support for a 10 W power handling VPIN limiter from Qorvo. The TGL2217-SM protects receiver chains in commercial and military radar, communications systems and electronic warfare applications. Providing frequency coverage from 100 MHz to 20 GHz, flat leakage power is <18. 5 dBm. Both input and output ports are matched to 50 ohms with return loss of >15 dB. 
SemiGen Inc. has added a series of fixed attenuator pads to its expanding product offerings. SemiGen offers a selection of fixed attenuators pads with an attenuation of 0 to 100 dB. These attenuator pads feature precise resistor films and superior metallization resulting in a flat response from DC to up to 50 GHz. Attenuator pads offer power handling from 1 to 5 W continuous wave.
TRAK, a Microwave brand of Smiths Interconnect, has announced it has added a 4-port, ferrite-based, C-band circulator to our line of products. Integrating forward and reverse power detectors that operate up to 75 W CW, TRAK offers radar and communications systems designers a unique solution for reducing components and lowering costs while striving to enhance signal clarity.
SemiGen Inc. is offering a series of mounting capacitors that can be screen to class K quality requirements for space. SemiGen’s ideal low loss very high Q mounting capacitors feature low temperature coefficients. With six different capacitances offered from 45 pF to 1000 pF, these capacitors are developed using an MNOS approach and precision photolithography to provide a dependable device.
Richardson RFPD Inc. announced the availability and full design support capabilities for a series of high-power SMT attenuators from ATC. The AT0603 Series provides virtually flat loss over a broad frequency spectrum and is ideal where low noise, low inductance and low parasitic capacitance is required. The film metallization provides stable characteristics over temperature and time.
Isolators and Circulators covering X and Ku bands (8 to 12.4 and 12.4 to18 GHz) with SMA-female connectors with average power ratings to 50 W (forward) and 2 W(reverse). With min spec’s of; 1.30:1 VSWR, 0.4 dB insertion loss and 18 dB isolation min.
