MONOTONICITY:
10 MHz to 2.5 GHz
3rd ORDER INTERMODULATION (IM3):
-30 dBm typical,
measured with two +27 dBm tones @ 869 MHz (f1) and
894 MHz (f2), the IM3 frequeny being 847 MHz (2fl-f2).
IP3
(input) = +53 dBm
The input IP3 is derived from the following relationship:
IP3 = 3(Pin-
α
)-IM3 +
α
2
where
α
= the insertion loss (dB) at the IM3 frequency;
Pin=single tone input power (dBm).

CONTROL CONFIGURATION:
Units are supplied with a
built-in TTL interface. Each unit is supplied with a mating 10
pin connector (Amp 746285-1). Refer to Physical
Dimensions for mating connector pin/wiring details. Two
wires are specified for supply voltage and ground. The
remaining wires will accept TTL control signals to activate
or de-activate a particular attenuation cell. A TTL high will
energize a cell to the high attenuation state, whereas a TTL
low will maintain a cell in its zero attenuation state.
