Our cavity bandpass filters for 700 MHz LTE are available for all uplink and downlink bands and meet the stringent requirements posed by dense channel spacing. They have more than 40 dB of rejection at 700 kHz from passband to stopband at band edges, low insertion loss, and PIM as low as -150 dBc.
PMI Model No. P8T-500M40G-60-T-55-292FF is a high speed, single pole, eight throw, absorptive switch operating over the frequency range of 0.5 to 40 GHz. This switch has over 60 dB of isolation and is capable of switching within 50 ns.
Renaissance has designed a 12 x 12 programmable delay line (PDL) matrix that can be used to simulate targets for phased array radar and receiver optimization. Each of the 12 inputs is connected to dividers, programmable attenuators and a programmable delay line matrix.
Renaissance has developed a new solid state programmable attenuator that can be used to perform fading simulations. The device operates from DC - 3 GHz with 5.5 dB insertion loss and can attenuate 100 dB in 1 dB steps. The attenuator can handle 20 dBm over -40 to +85 C.
Renaissance Electronics has developed a new low PIM attenuator perfect for ATE applications which covers DC to 3.0 GHz. Available in multiple attenuation values and handling 100 W CW, the attenuator exhibits -145 dBc of PIM distortion; making it ideal for test applications which require extremely low PIM.
Two new high performance directional couplers from AtlanTecRF cover the entire frequency range from 375 MHz to 18 GHz with at least 3 GHz of overlap. Available in a choice of either 10, 20, or 30 dB the 50 W couplers with SMA connectors and built-in terminations will operate over a temperature range of -55 to +55° C, making them suitable for use in applications from airborne ECM to the benign test bench.
Linear Technology Corp. introduces the LTM2892, a 6-channel SPI/digital or I²C µModule® (micromodule) isolator for 3.3 to 5 V systems. Ground potentials can vary widely in systems, potentially exceeding common mode operating limits, which can interrupt communications, destroy components, and even create hazardous conditions.
The AM1485DC854 30-dB dual-directional coupler operates from 800 to 2170 MHz, handles 500 W average and 3 kW peak RF power input, and is well suited for base station RF power monitoring. It has very low third-order intermodulation distortion of -155 dBc, insertion loss of 0.5 dB, coupling flatness of 0.75 dB, directivity of at least 25 dB, and VSWR of 1.07:1.
The AM5725B1162ceramic bandpass filter has a center frequency of 5725 MHz, a 1-dB bandwidth of 90 MHz (5680 to 5770 MHz), insertion loss of 5 dB or less, passband ripple of 1.2 dB or less, return loss of at least 12 dB, and rejection of at least 30 dB at 5525 MHz and 5925 MHz.
The AB907B781 cavity bandpass filter is designed for outdoor applications and has a center frequency of 907.5 MHz, 1.5-dB bandwidth of 905 to 910 MHz, insertion loss of 3 dB or less, and out-of-band rejection of at least 75 dB from 850 to 889 MHz and 919 to 950 MHz.
