FEATURES
• Sheet multilayer construction has resulted light weight chip
diplexers(L3.2
×
W1.6
×
T1.1mm, 18mg).
• The industry’s smallest class diplexers maintain high grade, high
stability characteristics for dual band/dual mode cellular trans-
mission and reception. These diplexers have good separation
characteristics, achieving both low insertion loss and high stop-
band attenuation.
• This series provides a choice of two product types corresponding
to the most typical dual band systems:AMPS/PCS1900(USA)
and EGSM/DCS1800(Europe).
• Since these diplexers are provided with outstanding resistance
to damage from the physical and chemical environment, stable
characteristics are maintained, even for cellular applications
under severe conditions.
