Second generation of surface-mount (SMT II) isolators and circulators, with frequency ranging from 800 MHz to 3.8 GHz. The SMT II devices are designed for low IMD application, PCB application, with very compact package and soldering reflowing durability. Minimum isolation is 20 dB, maximum insertion loss 0.35 dB, -75 dBc IMD with custom design available upon request.
Coupler Model 120406 enhances the product line with performance ratings including nominal coupling (with respect to output) of 6 dB, ±0.5 dB, and frequency sensitivity of ±0.30 dB. The directional coupler exhibits insertion loss (including coupled power) of less than 1.8 dB, directivity of greater than 15 dB, maximum VSWR (any port) is 1.35, input power rating is 20 W average and 3 kW peak. Operating temperature is -54° to 85°C.
DiTom Microwave has released a new Ka-Band (27-31 GHz) space qualified isolator. The DS1017 is manufactured to meet or exceed environmental space-level reliability including thermal shock, sine and random vibration, temperature cycling, and thermal vacuum survivability over a specified qualification and acceptance test plan.
3H Communication Systems model number XLCN400-30-7SS, is a leadless SMT bandpass filter with a notch integrated into the passband. Insertion loss at 235 to 345 MHz is < 2.0 dB and < 2.5 at 435 to 465 MHz. The notch band is centered at 400 MHz with a 30 MHz notch band of >15 dB attenuation. The filter size is 0.74 L x 0.44 W x 0.27 H" and is suitable in tape and reel packaging.
Krytar's directional coupler Model 106026506 delivers 6 dB (±0.5 dB) of nominal coupling (with respect to output) and frequency sensitivity of ±0.50 dB. Directivity is >14 dB. The coupler exhibits insertion loss of <1.6 dB across the full frequency range including coupled power. Maximum VSWR at any port is 1.45, input power rating is 20 W average and 3 kW peak. Operating temperature is -54°C to +85°C.
3H Communication Systems designs and manufactures a complete line of Public Safety filters and multiplexers for First Responders for Land, Mobile, Marine and Aeronautical markets. The filter products are suited for VHF, UHF, 700, 800, 900 MHz and Tetra Bands. 3H filter products offer low insertion loss and >60 dB Co-Channel isolation.
Vaunix has announced the addition of a new 75 ohm model to their family of LDA series digital attenuators. The LDA-102-75F has input power of up to 1 W, attenuation range to 95 dB, and offers frequency coverage of 10 to 1000 MHz. This unit is powered and controlled by connection to a PC or self-powered USB hub, and is programmable for fixed attenuation or swept attenuation ramps directly from the included graphical user interface (GUI) software.
