Features  
MONOTONICITY: 10 MHz to 2.5 GHz  
Ideal for use in Wireless/Cellular, RF simulation/Emulation,  
& Communication Test Applications.  
3rd ORDER INTERMODULATION (IM3): -43 dBm typical,  
measured with two +27 dBm tones @ 869 MHz (f1) and  
894 MHz (f2), the IM3 frequency being 844 MHz (2fl-f2).

Broadband Performance - 10 MHz to 2.5 GHz  
High IP3 and High Power Rating  
- Utilizes MESFET Switching  
IP3 (input) = +58 dBm  
The input IP3 is derived from the following relationship:  
o
o
Flexible DC Voltage (+5 to +15 V)  
Low DC Power Consumption - Ideal for portable  
battery powered equipment.  
IP3 = 3(Pin-α)-IM3 + α  
2
where α = the insertion loss (dB) at the IM3 frequency;  
Pin=single tone input power (dBm).  
POWER RATING: 4 Watts maximum  
SWITCHING TIME: 5 μsec. maximum  
OPERATING VOLTAGE: + 5 V to +15V  
OPERATING CURRENT: 25 mA typical
