PROGRAMMABILITY: In each programmable step

Attenuator, solenoids are used to switch the internal resistor

card of each cell into and out of the circuit. Once the cell is

switched, the solenoid is magnetically latched into position

and is able to withstand extreme shock and vibration.

Internal circuitry is included to interrupt the coil current after

switching is complete. This reduces power dissipation even

if power is continuously applied. The switching time for each

cell is rated at 20 msec maximum which includes the con-

tact settling time.

BROADBAND ACCURACY & LOW SWR: The use of

Aeroflex / Weinschel's proprietary thin-film resistor process

provides these programmable step attenuators with a high

degree of accuracy and the lowest possible SWR uncer-

tainty (refer to specifications for actual values). This thin film

process permits the construction of circuits which are truly

distributed and without stray reactances, even at the higher

microwave frequencies.

Description

The Model 150, 151 and 152 Programmable Step

Attenuators represent the widest variety of programmable

attenuators available. This attenuator design is the result of

an extensive development program and offers long reliable

operation with exceptional accuracy and repeatability.

These attenuators can provide programmable adjustments

of RF signal levels in precise steps of 1 dB, 5 dB, 10 dB, or

with custom steps available. Each attenuator consists of a

cascaded assembly of

RELIABILITY:

Each programmable step attenuator is

composed of 3 to 5 (4 in most models) cells. As with all

mechanical designs, usable life becomes a primary concern

to the user. With this in mind Aeroflex / Weinschel backs all

these attenuators with a rated switch life of 5 million

operations per cell. Standardized testing is also performed

on each programmable step attenuator over its operating

frequency range by a computer controlled Aeroflex /

Weinschel Attenuation Measurement System which is

traceable to NIST standards.

switched attenuator cells

(Figure 1). The attenuator

elements located in the

attenuator cell are created

a thin-film process

which provides excep-

tional long-term stability,

low power and tempera-

ture coefficients. This

series uses a reed switch-

ing structure that provides

rapid switching together

with low insertion loss.

ENVIRONMENTAL: These Model 150 Programmable Step

Attenuators have undergone an extensive environmental

qualification program and have been subjected to

temperature, shock, vibration, and humidity conditions per

MIL-STD-202F. These programmable step attenuators

operate within these specifications at an ambient

temperature of -20° to +75°C. Operating beyond these

limits will adversely affect the accuracy and could damage

the internal circuitry.
