1. Digital phase shifters in the PTM-84B series are controlled

directly by TTL and are available for frequencies from 100 to

500 MHz.

1.3:1 max.

Insertion Loss, I_L:

2.5 dB nom., 4 dB max.

2. Each model provides 360° of phase shift at a selected

calibration frequency in 8 binary increments (255 steps)

resulting in 1.4° resolution.

3. Phase shift is based on propagation delay through precisely

calibrated cables. Selecting a specific phase shift is

accomplished by entering a digital word that in turn switches in

appropriate delay lines through fast-acting PIN diodes.

I_LVariation vs. Cont: ±0.2 dB @ mid band

Control Input:

+10 dBm max.

Logic Sense:

Supply Power:

+5 VDC@500 mA max.

+15 VDC@150 mA max.

1 ms max.

4. 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).

5. Phase shifters based on switched cables are inherently stable

and well matched. Each bit can be set and held very closely in

binary increments from the LSB to the MSB (Most Significant

Bit).
