RFMW, Ltd. announces design and sales support for a pair of 100 W VPIN limiters from TriQuint. The TGL2206-SM covers applications falling from 2 to 5.5 GHz while the TGL2207-SM extends the range from 2 to 6.5 GHz. Both limiters offer <1 dB insertion loss and neither the TGL2206-SM nor TGL2207-SM require DC bias. Input/output return loss measures 15 dB.

Pasternack’s new 1.85 mm attenuators come in 3, 6, 10, 20 and 30 dB values and are rated to 65 GHz at 1 W. The 1.85 mm RF terminations are also rated to 65 GHz at 1 W and have a VSWR of 1.3:1 to 40 GHz and 1.65:1 to 65 GHz. The 1.85 mm connector interface, also referred to as a “V Connector®”, is widely used in satellite communications (VSAT) equipment, point-to-point radios, WiGig applications and millimeter-wave radars.

RFMW, Ltd. announces design and sales support for Peregrine Semiconductor’s 2-bit, fast-switching digital step attenuator (DSA). The PE43205 offers 29 nS switching time when transitioning between 6, 12 or 18 dB of attenuation. Specified from 35 MHz to 6 GHz, the PE43205 offers IIP3 of 61 dBm for highly linear, wide dynamic range circuits.

RFMW Ltd. announces design and sales support for adual-band SAW filter module from TriQuint. TheTQQ1212 serves band 34 (2010 to 2025 MHz) and band 39 (1880 to 1920 MHz) in a single, 4x3 mm module. Band 34 passband bandwidth is 15 MHz while band 39 has a 40 MHz bandwidth. Insertion loss in both bands is 3.8 dB max.

RFMW Ltd. announces design and sales support for Peregrine Semiconductor’s new, adjustable power limiter providing protection for up to 50 W pulsed RF input. For CW applications, the PE45140 handles up to 10 W of power. The adjustable power limiting threshold, from +22 to +32 dBm, enables flexibility across different platforms and architectures.

Richardson RFPD Inc. announced the availability and full design support capabilities for two series of precision tolerance, NP0 RF microwave capacitors from American Technical Ceramics Corp. (ATC). The high-frequency, low-loss (Hi-Q) 400L series and 400S series capacitors feature a precision thin-film process that provides reliable and repeatable performance, and high series resonant frequency.

For SATCOM on-the-move (SOTM) terminals, Renaissance has designed a compact low loss isolator with K-connectors to support the bandwidth requirement of 27.35 to 31.7 GHz. The power handling on this model is 10 W forward and 1 W reverse, but this package can be customized for up to 50 W forward and 10 W reverse.

For SATCOM on-the-move (SOTM) terminals, Renaissance has designed a compact low loss isolator with K-connectors to support the bandwidth requirement of 27.5 to 30.5 GHz. The power handling on this model is 10 W forward and 1 W reverse but this package can be customized for up to 50 W forward and 10 W reverse.

To protect space communication payload electronics, Renaissance has designed a 26.5 GHz microstrip isolator. The main features include compact size, low loss and high isolation. This device meets all of NASA's outgassing requirements. Some of the benefits include the capability of being used for space or harsh environments, protection of expensive amplifier circuits and optimization for space constrained applications.

Pasternack Enterprises Inc., an industry leading manufacturer and supplier of RF, microwave and millimeter wave products, announces their expanded line of 75 Ohm F attenuators. This new line of F-type attenuators is perfect for broadcast, HDTV and satcom applications in the L and S microwave bands up to 3 GHz. Pasternack’s new F attenuators are available in 1 to 10 dB values in 1 dB steps.
