Specifications 50 Ω 0.2 to 3.0 GHz NOMINAL IMPEDANCE: FREQUENCY RANGE: CELL CONFIGURATIONS: Model Number 4203-31.75 Attenuation Range/Steps (dB) Attenuation Increments (dB) 0 -31.75 / 0.25 0.25, 0.5, 1, 2, 4, 8, 16 4203-63 0-63 / 1 MAXIMUM SWR: POWER RATING: SWITCHING SPEED: CONTROL LOGIC: OPERATING VOLTAGE: 1.4:1 +24 dBm maximum 1 μSec maximum TTL +5 V @ 20 mA TEMPERATURE RANGE: 0°C to + 70°C TEST DATA: Test data can be provided at additional cost. CONNECTORS: SMA female connector - mates nondestructively with other SMA connector per MIL-C-39012, 3.5mm and other 2.92mm connector. CONTROL CONNECTOR: AMP-Latch 10 pin ribbon cable connector mates with AMP P/N 746285-1 (supplied with each unit) 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.
