MONOTONICITY: 4226-63 & 4228-103: 0.8 to 3.0 GHz

4228-63.75:

0.8 to 2.5 GHz

(minimum 1 dB

change)

3rd ORDER INTERMODULATION (IM3): -55 dBm typical,

measured with two +10 dBm tones @ 869 MHz (f1) and

891 MHz (f2), the IM3 frequency being 847 MHz (2f1-f2).

Features

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

& Communication Test Applications.

IP3 (input) = +41 dBm

The input IP3 is derived from the following relationship:

Available in 6 and 8 Cell Configurations -

103 dB/1 dB steps

IP3 = 3(Pin-α)-IM3 + α

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

Pin=single tone input power (dBm).

63 dB/1 dB steps

63.75/0.25 dB steps

High accuracy & fast switching speed

Built-in TTL Driver Circuitry

POWER RATING: +24 dBm operating

Special Configurations Available Upon Request.

+30 dBm (1 dB compression point)

Custom Cell/Step Size & Frequency Bands

SWITCHING TIME: 2 μsec. maximum

OPERATING VOLTAGE: +5 V + 5% @ 160 mA for 6 cell/

200 mA for 8 cell typical

Specifications

NOMINAL IMPEDANCE: 50 Ω

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

TEMPERATURE COEFFICIENT: < 0.002 dB/dB/°C

CONNECTORS: SMA female connectors - mate nonde-

structively with MIL-C-39012 connectors.

FREQUENCY RANGE: 4226-63:

0.8 to 3.0 GHz

4228-63.75: 0.8 to 2.5 GHz

4228-103:

0.8 to 3.0 GHz

0.8 - 3.0 (2.5)

WEIGHT:

4226-X 160 g (5.7 oz)

4228-X 210 g (7.4 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.
