Designed for demanding infrastructure applications, EMC’s 32P7197F operates to 2GHz with a maximum VSWR of 1.25:1. This termination can handle peak powers up to 1100 watts based on a 10 microsecond pulse width with one percent duty cycle. Featuring a tab launch and integrated heat sink, the 32P7179F finds applications in mobile network infrastructure, broadcast amplifiers, high power isolators and instrumentation. Nominal impedance is 50 ohms with…
In a recent Microwave Product Digest interview, RFMW, Ltd. President and CEO Joel Levine highlighted RFMW’s position as a specialized distributor of RF and microwave components and the challenges that lay ahead in the ever evolving consumer and military markets. Read the article.
The TriQuint 856774 SAW filter is specifically designed for low signal distortion in both amplitude and phase response. Ideal for 3G and 4G infrastructure applications, the 856774 is centered at 140MHz with a 56MHz bandwidth. Greater than 40dB attenuation and flat in-band performance combine to offer very low EVM contribution in high performance, wideband communication systems. TriQuint’s 856774 140MHz SAW filter can be used in either balanced or single-ended circuits and is housed in a hermetic, ceramic, surface-mount package measuring only 9.1×4.8×1.24mm.
RFMW , Ltd. announces application and sales support for the Telemakus TEP4000-5 digital phase shifter. This laboratory quality phase shifter has a minimum phase range of 360 degrees with 12-bit, 0.25 degree resolution and operates over the bandwidth of 2 to 4GHz. Maximum RF input for linear operation is +6dBm but the device can handle up to +20dBm. Typical insertion loss through the TEP4000-5 is only 5dB. When coupled with the TEA4000-7 USB controlled RF attenuator, a gain and phase control system can be created. Applications include phased array antenna testing. Weighing less than an ounce each, Telemakus test devices…
RFMW, Ltd. announces design and sales support for two S-band power amplifiers from TriQuint. The TGA2583 and TGA2585 cover the frequency range of 2.7 to 3.7GHz with 10 and 18 watts of saturated output power respectively. Both TriQuint devices offer power added efficiency of 54% with a small signal gain of 33dB. Designed primarily for Radar applications, the TGA2583 and TGA2585 use TriQuint 0.25um GaN technology offering good thermal characteristics in either pulse or CW operation. Using a 25V bias, the TGA2583 draws 175mA while the TGA2585 draws 225mA. Both devices are currently available in 3×1.9mm die with 5×5 QFN…

RFMW, Ltd. announces the availability of a white paper discussing the proper selection of microwave absorbing and EMI shielding products. This Technical Bulletin from MAST Technologies defines the characteristic properties of various elastomers used in the manufacture of microwave absorbing products. For example, Nitriles show excellent resistance to petroleum based fuel and oil products so are superior to Silicone in aerospace and flight line environments. For high temperature applications or where dilute acids may be encountered, a Viton based absorber may be the best option. MAST Technologies’ elastomer based absorbers are used in a variety of commercial and military applications…
RFMW, Ltd. announces design and sales support for the TGA2594, a 5W high-power amplifier developed using TriQuint’s GaN15 technology. Supporting VSAT and SATCOM applications, the TriQuint TGA2594 offers 35dBm P1db or 37dBm Psat from 27 to 31GHz. Small signal gain is up to 23dB.
