Features Model Number 4208-63.75 Accuracy + 0.4 dB or 2.0% The input IP3 is derived from the following relationship: IP3 = 3(Pin-)-IM3 + 2 where = the insertion loss (dB) at the IM3 frequency; Pin=single tone input power (dBm). *POWER RATING (Undirectional): Model J1 J2 4206-XX 4 Watts MAX IN (+36 dBm) 2 Watts MAX IN (+33 dBm) 4208-XX 2 Watts MAX IN (+33 dBm) 4 Watts MAX IN (+36 dBm) SWITCHING TIME: 5 sec. maximum OPERATING VOLTAGE: + 5 to +15 V OPERATING CURRENT: 25 mA typical TEMPERATURE RANGE (Operating): 0C to +70C TEMPERATURE COEFFICIENT: <0.002/dB/dB/C CONNECTORS: SMA female connectors - mate nondestructively with MIL-C-39012 connectors. CONTROL CONNECTOR: AMP-Latch 10 pin ribbon cable connector mates with AMP P/N 746285-1 (supplied with each unit) WEIGHT: 4206-X 160 g (5.6 oz) 4208-X 220 g (7.7 oz) 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. 5305 Spectrum Drive, Frederick, MD 21703-7362 TEL: 301-846-9222, 800-638-2048 Fax: 301-846-9116 web: www.weinschel.com email: sales@weinschel.com PHYSICAL DIMENSIONS: Models 4206 & 4208: J1 J2 Control Connector J3 Pin Locations: Model No. A B C 4206-X 09.0 (4.33) 96.5 (3.80) 76.2 (3.00) TTL Conn PIN No. (J3) 4206-63 dB (Cell) 4208-63.75 dB (Cell) 4208-X 143.5 (5.65) 110.2 (4.34) 110.2 (4.34) 1 1 0.25 2 2 0.50 3 4 1 4 8 2 5 16 4 NOTE: All dimensions are given in mm (inches) and are maximum, unless otherwise specified. 6 32 8 7 NC 16 8 NC 32 9 +5 to 15V +5 to 15V 10 COM COM NC = Not Connected 5305 Spectrum Drive, Frederick, MD 21703-7362 TEL: 301-846-9222, 800-638-2048 Fax: 301-846-9116 web: www.weinschel.com email: sales@weinschel.com 149 4/30/02
