Specifications	APP Note:111
Frequency Range	2 – 18 GHz	Designed to meet the following Environmental Conditions: Operating Case Temp.: -40 to +85°C Storage Temp.: -54 to +105°C Mechanical Shock: Per MIL-STD-810F, Method 516.5 Vibration: Per MIL-STD-810F, Method 514.5 Humidity: Per MIL-STD-810F, Method 507.4 Mechanical: SMA Connectors Altitude: Per MIL-STD-202, Method 105,Cond. C Except @ 60,000 Ft. Weight: 3.5 oz. Volume: 0.95 cu in. Material: S303 Finish: Gold Plating per MIL-G-452041 Control Pins: J1: Ground J2: TTL input. Controls Dynamic Range externally TTL1: -60 to +10 dBm TTL0: -75 to -5 dBm No connection or high impedance >10K ohm will be automatic. J3:* Analog output which determines the signalstrength of stray cw signal. J4: TTL output: Determines in what dynamic range the unit is operating. TTL1: -60 to +10 dBm TTL0: -75 to -10 dBm -Normally, the unit is in high sensitivity mode (-75 to -5dBm). -At the presence of a high level stray cw signal, the unit automatically switches to (-60 to +10 dBm) within 50 nsec, unless it is overridden by external TTL Control (J2).
