TT electronics IRC advanced film division has released a high power attenuator and surface mount transmission line terminator targeted for RF and microwave applications.

The PAT3060P Series attenuator and RFTF Series terminator feature low VSWRs at high frequencies, providing a combination of power dissipation and performance in the RF and microwave bands.

The PAT3060P Series attenuator and RFTF Series terminator are designed for high frequency and high power applications including RF power meters, RF and microwave power amplifiers, radar, satellites, avionics, wireless communications, RF power sources and RF/microwave test instruments.

The PAT3060P high power attenuator features a frequency range from DC to 10GHz with a VSWR of less than 1.3 at 10GHz. Attenuation values include 0- 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-, 16- and 20dB. The attenuator is rated to 10W when heatsinked (1.5W without a heatsink). Impedance is 50? operating temperature of -55C to +125C.

The RFTF Series high frequency terminator is available with power ratings to 250W. Stray capacitance is "The construction of these devices maximizes performance at RF frequencies at high power dissipation," said Jerry Seams, applications engineering manager for IRC. "The terminator combines the benefits of planar design with the high thermal conductivity of aluminum nitride, while the attenuator is offered in a flanged package for direct heat sink mounting."

Pricing for the PAT3060P attenuator starts at $10.50 each in 50-piece quantities. Pricing for the RFTF Series terminator starts at $8.75 in 100-piece quantities. Lead time is 6 weeks for the PAT3060P and 8 weeks for the RFTF.
