Design Guidelines for TERIDIAN 78P235x LIUs
TRANSFORMER SELECTION
The 78P235x LIUs use 1:1CT (center-tapped) wide band transformers for both transmit and receive ports. These
wideband transformers must exhibit the following characteristics:
?
?
?
?
?
?
75 Ω impedance (primary and secondary)
Max RF power: ~250mA
Max DC current: ~30mA
Avg. Insertion loss: 1dB max
Return loss: Min 16dB (7 –250 MHz)
Frequency Response:
The bandwidth or frequency response of available transformers can range from
400MHz to 800MHz. For some system environments, more bandwidth-limiting
transformers can help eliminate the overshoots that can cause pulse mask failures. Too
narrow of a bandwidth will result in a rounded transmit pulse shape and receiver
sensitivity to binary CMI zeroes at max cable loss.
To provide system designers with greater flexibility, Teridian has evaluated and approved multiple vendors in
compatible SMT footprints. The following table lists the recommended single and dual transformers from different
vendors.
NOTES:
1. To request test data on any of the listed transformers or to get an updated list of qualified vendors, please
send an email to: wan.support@teridiansemiconductor.com
2. Pinout naming conventions can vary from vendor to vendor, but all winding diagrams should match those
found in Figure 9.
