Features  
MONOTONICITY: 10 MHz to 2.5 GHz  
Ideal for use in Wireless/Cellular, RF Simulation/Emulation,  
& Communication Test Applications.  
3rd ORDER INTERMODULATION (IM3): -60 dBm typical,  
measured with two +27 dBm tones @ 869 MHz (f1) and  
894 MHz (f2), the IM3 frequency being 847 MHz (2fl-f2).  
o
Broadband Performance - 10 MHz to 2.5 GHz  
usable dc to 10 MHz with reduced specifications  
IP3 (input) = +65 dBm  
The input IP3 is derived from the following relationship:  
IP3 = 3(Pin-α)-IM3 + α

High IP3 and High Power Rating  
- Utilizes MESFET Switching

Flexible DC Voltage (+5 to +15 V)  
Low DC Power Consumption - Ideal for portable  
battery powered equipment.

CELL CONFIGURATIONS:  
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.
