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…
Telemakus LLC has announced a price reduction of their model TEP8000-6, digital phase shifter. This USB controlled device offers 360 degrees minimum phase range with 12-bit, 0.25dB resolution over the frequency range of 4-8GHz. Maximum RF input for linear operation is +10dBm. Typical insertion loss through the TEP8000-6 is only 5dB. When coupled with the Telemakus TEA8000-6 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 represent the latest technology in low cost, transportable test equipment. Each unit’s graphical user interface…
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. Designers will appreciate the small DIE size of 3.24×1.74mm and can expect improved linearity over similar devices currently offered. Operating from a 20V bias, the TGA2594 draws 140mA. Power added efficiency ranges to 28%.
RFMW, Ltd. announces design and sales support for TriQuint’s T1G2028536, a 285W GaN transistor available in a low thermal resistance, solder mount package as the T1G2028536–FS or flange mount package as the T1G2028536–FL. Both the –FS and -FL house the transistor in a ceramic NI-780 enclosure. Operating from DC to 2GHz, the T1G2028536–FS and T1G2028536–FL provide 18dB of linear gain at 1.2GHz and operate from a 36V source drawing 576mA. Applicable to commercial and military radar, both T1G2028536–FS and T1G2028536–FL are input prematched for L-band operation. Additional applications include professional and military communications, wideband amplifiers and avionics. Both devices boast…
RFMW, Ltd. announces design and sales support for two internally matched, high IP3 low noise amplifiers from TriQuint. The TQL9042 and TQL9043 both feature bypass switches and shut-down pins offering receivers the highest level of sensitivity performance. The TQL9042 offers 19dB gain over 0.5 to 2GHz with a market leading 0.42dB noise figure. The TQL9043 provides frequency coverage from 1.5 to 2.7GHz with >18dB gain and 0.5dB noise figure. TriQuint’s TQL9042 and TQL9043 bypass switch loss measures 1dB and 1.6dB respectively. Both LNAs find applications in BTS transceivers, whether TDD or FDD, as well as small cell radios. Their frequency…
RFMW, Ltd. announces design and sales support for the TGA2813, a 100W GaN power amplifier targeted for RADAR applications from 3.1 to 3.6GHz. TriQuint’s TGA2813 offers 55% PAE supporting both short and long pulse operation with good thermal properties. Large signal gain is up to 22dB. 30V bias draws a quiescent current of 135-550mA as TriQuint’s bias flexibility supports a variety of system requirements. The TGA2813 is available as a 5.4 x 6.7 x 0.1mm DIE with blocking caps on both RF ports matched to 50 ohms making this TriQuint GaN PA ideal for commercial and military RADAR systems.
