The SKY16706-11 is a dual coupler module (DCM) that consists
of two bidirectional couplers with coupled path filtered with a
filter optimized for 2.4 GHz and 5 GHz rejection. SKY16706-11
has 50 Ω input and output impedance with internal DC blocking
and minimal number of external support components. The DCM
is targeted for use in mobile applications. It is compatible with
3GPP GSM, WCDMA, LTE and LTE-A standards and supports the
B1, B2, B3, B4, B7, B30, B34, B39, B38, B40, and B41 service
bands: for the cellular part. It also supports GPS/GNSS/Beidou
The SKY16706-11 is packaged in a compact 16-lead,
1.6 × 1.6 × 0.54 mm surface mount package that meets
requirements for board-level assembly.
No external DC blocking capacitors are required on the RF paths
as long as no DC voltage is applied. The DCM can operate over
the temperature range of –35 °C to +90 °C.
