Description
Aeroflex / Weinschel’s new line of MMIC Digital Attenuator
operates over the 0.4 to 6 GHz frequency range and pro-
vides an attenuation range from 0 to 63 dB in 1 dB
increments.
Specifications
NOMINAL IMPEDANCE: 50 Ω
FREQUENCY RANGE: 0.4 to 6.0 GHz
ATTENUATION RANGE/STEPS: 0-63 in 1 dB steps
ATTENUATION INCREMENTS: 1, 2, 4, 8, 16, 32 dB
ATTENUATION ACCURACY: +1 dB or 4%
INSERTION LOSS: 7.0 dB maximum
SWR: 2:1 maximum
POWER RATING: 20 dBm (100 mW) maximum
SWITCHING SPEED: 300 nsec maximum
CONTROL LOGIC: TTL
OPERATING VOLTAGE: +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 nonde-
structively 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.
