PMI Model No. TDC-30T-0110-CD-1 is a high speed, TTL logic output threshold detector with an input coupler designed to operate from 0.1 to 10 GHz. Specifications include 0.1 to 10 GHz frequency range, 2.5 dB max insertion loss and 2.0:1 VSWR. Finish is gold plated.

PMI Model No. SDLVA-2020-OPT112 is a truly DC-coupled successive detection log video amplifier (SLDVA) that has 40 dB dynamic range over the frequency range of 1.0 to 12.0 GHz and provides an 8-bit digital log video output. The unit employs planar diode detectors and integrated video circuitry for high speed performance and outstanding reliability. 

Engineers often have specific requirements which may not be available in the standard range of products.  AtlanTecRF recognises this all too familiar problem by demonstrating how they are able to optimise, customise or design a specific solution depending on what the customer needs with the release of over 120 drawings across 19 component categories into an online Engineering Library on their website.

RFMW Ltd. announces design and sales support fora 50 W, surface mount, directional coupler serving 15 to 18.5 GHz applications. The EMC Technology DN05W20F provides a 20 dB coupling factor with only 0.6 dB insertion loss. Directivity is 32 dB min from 17 to 18.5 GHz while the DN05W20F maintains a maximum VSWR of 1.6:1.

Pasternack announces the release of their new 5 Bit, 8 Bit and 10 Bit broadband PIN diode digital step attenuators with performance up to 40 GHz depending on the configuration. The digital step attenuators come in 30 dB and 60 dB values and have attenuation step resolution of 0.25 dB to 1 dB depending on the model.

Passive Plus Inc. offers a line of Hi-Q/Low ESR Capacitors available in 4 case sizes. C series: 2225, 3838, 6040, and 7676. These multilayer capacitors are ultra-reliable and can be used in demanding high RF current and voltage applications. Products are available in surface mount or leaded configurations that are 100% RoHS compliant. These products are also available in a Non-magnetic termination.

KRYTAR Inc. announces Model 7030400, a 4-way power divider offering high performance over the ultra-broadband frequency range of 3 to 40 GHz with >13 dB Isolation and ±0.5 dB amplitude tracking. The 4-way divider exhibits insertion loss of <3 dB from 3 to 32 GHz and <3.6 dB from 32 to 40 GHz. The 4-way power divider can also be manufactured to meet military specifications.

RFMW Ltd. announces design and sales support fora 50 W, surface mount, directional coupler serving 14.5 to 19.7 GHz applications. The EMC Technology DN05Z15F provides a 15 dB coupling factor with only 0.5 dB insertion loss in the main band of 15 to 19 GHz.  Directivity is a strong, 28 dB min. Maximum VSWR in the DN05Z15F main band is 1.3:1. As a purely passive device, reliability is assured. 

RFMW Ltd. announces design and sales support for ten new surface mount circulators from RFCI. Available at popular base station frequencies from 728 to 2690 MHz, these pin-style, surface mount circulators offer 500 W peak forward power handling and 80 to 100 W reverse power handling depending on package size.

RFMW Ltd. announces design and sales support for a temperature compensated voltage controlled attenuator. RFMD's RFSA2013 provides a linear attenuation slope versus control voltage with very little sensitivity to temperature changes. Built on SOI technology, linearity exceeds that of FET based designs. IIP3 linearity of the RFSA2013 is >50 dBm.
