General Notes:

1. PTB- & PTM-84A series phase shifters provide up to 360° of phase shift at a

selected calibration frequency in 8 binary increments (255 steps) resulting in 1.4°

resolution. Each step is generated with different cable lengths switched with PIN

diodes. Advantages of the switched-line phase shifter over the digitally controlled

analog type include potential for higher accuracy and smaller value of the Least

Significant Bit (LSB).

2. Phase shifters based on cable switching are inherently stable and well

matched. Phase shift can be set and held very closely in binary increments from

the LSB to the MSB (Most Significant Bit).

3. This series can be calibrated up to 100 MHz and used to 180 MHz while the

related PTM-84B series extends coverage to 500 MHz.
