Dual PLL System – Ku Band

LNA / PLL BDC system for simultaneous reception of Low & High Ku-Band

• Wide frequency range
• Choose between Internal Ref. or External Ref. input models
• Several LO frequencies
• Low phase noise
• High P1dB and IP3
• Wide operating temperature range
• BDC’s for outdoor use
• Option Low profile to it 1U for build-in

Options available.

Choose options below, you have to fill in all fields. N/A = empty field.

To start over with new options


The Dual PLL is the professional solution to receive the two bands simultaneously with high LO stability and low phase noise.
Any LO frequencies can be combined without spuriouses e.g. Low band 10.0 GHz & High band 11.3 GHz.
The standard solution for Ku-Band Dual System consists of one LNA and two Block Down converters including RF and DC cables 3-6 m. All parts are optimized, adjusted and tested as a
complete matched unit.
