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).
