L = 25-50 MHz, M = 50-300 MHz, U = 300-400 MHz
Upper range coupling ±0.75 dB
Above 1000 MHz, coupling flatness ±1 dB.
Insertion loss specification in L range may degrade up to 1dB at
cold temperature, -55°C
When only specification for M range given, specification applies
to entire frequency range.
Available only with SMA connectors
Denotes 75 Ohm model, for coax connector models 75 Ohm
BNC connectors are standard.
General Quality Control Procedures, Environmental
Specifications, Hi-Rel and MIL description are given in General
Information (Section 0).
Connector types and case mounted options, case finishes are
given in section 0, see “Case styles & Outline Drawings".
Prices and specifications subject to change without notice.
