Features

MONOTONICITY: 10 MHz to 2.5 GHz

Ideal for use in Wireless/Cellular, RF Simulation/Emulation,

& Communication Test Applications.

3rd ORDER INTERMODULATION (IM3): -60 dBm typical,

measured with two +27 dBm tones @ 869 MHz (f1) and

894 MHz (f2), the IM3 frequency being 847 MHz (2fl-f2).

Broadband Performance - 10 MHz to 2.5 GHz

usable dc to 10 MHz with reduced specifications

IP3 (input) = +65 dBm

The input IP3 is derived from the following relationship:

IP3 = 3(Pin-α)-IM3 + α

High IP3 and High Power Rating

- Utilizes MESFET Switching

Flexible DC Voltage (+5 to +15 V)

Low DC Power Consumption - Ideal for portable

battery powered equipment.

where α = the insertion loss (dB) at the IM3 frequency;

Pin=single tone input power (dBm).

INPUT POWER RATING: +30 dBm

SWITCHING TIME: 5 μsec. maximum

Custom Configurations including bus controlled

attenuator subsystems

OPERATING VOLTAGE: + 5 to +15 V

Specifications

OPERATING CURRENT: 25 mA typical

TEMPERATURE RANGE (Operating): 0°C to +70°C

TEMPERATURE COEFFICIENT: <0.002/dB/dB/°C

NOMINAL IMPEDANCE: 50 Ω

FREQUENCY RANGE: 10 MHz to 2.5 GHz

CONNECTORS: SMA female connectors - mate nonde-

CELL CONFIGURATIONS:

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.
