4-Cavity TXRX 350W UHF Duplexer

At UHF, the TX RX Vari-Notch® design is the most commonly used. Vari-Notch® provides a low-loss pseudo-bandpass characteristic that can exist very close to a deep notch. Proven low-loss and low-noise construction techniques are used such as welded cavity construction; silver-plated loops, Alballoy®-plated integrated loop plates and connectors; as well as a unique fingerstock-free high-conductivity silver-plated tuning probe. Our cavities are constructed of hardened aluminum which, unlike most copper cavities, resists denting and associated detuning. All high RF-current components silver-plated for highest performance Vari-Notch® design provides low loss and high isolation. 406-430 MHz, 3.0 MHz Minimum Freq Separation 442-450 MHz, 5.0 MHz Minimum Freq Separation 450-470 MHz, 5.0 MHz Minimum Freq Separation Power Rating 350 W each model 0.8 dB Insertion Loss  (406-430 MHz) 100 dB  Isolation (406-430 MHz) 0.6 dB Insertion Loss  (442-450 MHz) 100 dB  Isolation (442-450 MHz)
