FEATURES
1. High frequency characteristics
(Impedance 50
Ω
, ~1.0GHz)
• Insertion loss; Max. 0.3dB
• Isolation; Min. 20dB
(Between open contacts)
Min. 30dB
(Between contact sets)
• V.S.W.R.; Max. 1.2
2. Surface mount terminal
This relay is a surface-mounted model
with excellent high-frequency properties.
In addition, it can use a microstrip line in
the base circuit design which spares the
labor of machining the base.
