  1. addoenoch134

    Hello, I’m making some duplexers (first time) I want to know if the TX and RX duplexers are the same, I mean they have both in TX and RX side an capacitor? because the RX side is opposite of the TX, how to get that reverse?

  2. zelatcol

    I have a combiner with 4 of these cavities in the 88 – 108 MHz band that I need to retune. How do I calculate the length of the cables?

  3. bianco.darci

    What is the valu or specification of Piston tuning capacitor in TPRD-1454?

  4. sv1edz

    Hello sir, band pass cavities are not good for 0,6 MHz spacing because they have very low reject value to so small spacing. This duplexer have about 90 to 100dB reject.

  5. shahmubashir983

    That means that you have very good isolation from TX to RX but nothing to filter the outside RF of the field.

  6. jabacomunicaciones

    Those should not be touched within the readjustment process of the cavities due to changes in frequency?, or if they should be adjusted to achieve an optimal fit?
