Werbel Microwave develops 10dB 0.5-6.0GHz couplers




Werbel Microwave continues to roll out excellent products suited for microwave test and measurement, D.A.S. and signal integrity applications.  
Our newest addition to the series of "brick" directional couplers currently in development is the 10-dB single directional coupler spanning 500-MHz to 6-GHz, continuously.
Preliminary specifications are as follows:
-----------------------------------------------
Coupling Tolerance: 10 +/- 1.0 dB
Coupling Flatness (Sensitivity): +/- 0.5 dB typ.
Directionality: 18 dB min.
Return Loss (all ports): 1.2:1 typ.; 1.3:1 max.
Insertion Loss: 0.9 dB max. (includes loss due to coupling split)
Prototype Test Data Plots to follow:
Coupling (UL).  Mainline Ret'n Loss (LL).  Coupled Ret'n Loss (LR)
Coupling (Magnified)
Directionality (UR).  Main Line Output Ret'n Loss (LL).  Coupled Ret'n Loss (LR).
Insertion Loss (UL).  Mainline Input Ret'n Loss (LL).  Mainline Output Return Loss (LR).

Werbel Microwave LLC is an independently-owned and operated designer and manufacturer of RF and wireless components.  Much of our work is custom, build-to-order.  Typical design-to-delivery is 6 weeks or less.

Werbel Microwave Develops 6-way Power Dividers




Werbel Microwave is developing a series of 6-way R.F. power dividers to cover bands up to 8-GHz.  Shown here is a model covering the 1.5-4.0GHz band.  Typical insertion loss is 1.0 dB or better with less than ±0.5 dB amplitude unbalance among output paths.  Phase balance is maintained at ±4 degrees maximum.  Typical isolation is 22dB or better (rated at 18dB min.) and typical worst case input/output VSWR's are 1.5:1 and 1.35:1, respectively.  Available with SMA or N female connectors.  Rated for 20W in splitting configuration.  IP-67 rated enclosure optional (type N connectors only).  Made in USA.
