SmartStep® Relay Switched Programmable Attenuators,
with built-in Microprocessor-Based Driver
For Use with Weinschel 8210A Controller
RoHS
The attenuator elements located in the attenuator cell are
created by a thin-film process which provides exceptional
long-term stability, low power and temperature coefficients.
This series of step attenuators uses a reed switching structure that provides rapid switching together with low insertion
loss.
Description
Aeroflex / Weinschel’s line of intelligent programmable step
attenuators with a built-in TTL interface (Figure 1). These
models are designed to simplify the control and integration
of these devices into subsystem and bench applications.
These intelligent attenuators offer the same long reliable
operation with exceptional accuracy and repeatability as
with our other 150 Series Programmable Attenuators. They
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 switched attenuator cells and a internal TTL interface.

BUILT-IN DRIVER CIRCUITRY:
These programmable
attenuators feature an internal microcontroller-based driver
that provides a TTL-level digital interface for control of the
attenuator relays. This card simplifies operation and interfacing requirements, while at the same time providing for
greatly enhanced flexibility over past designs. User selectable modes of operation include both parallel and serial
bus. The parallel mode provides a simple, one-bit per relay
on/off control with internal pullups for use primarily in single
attenuator applications. This mode allows the attenuator to
be controlled via a variety of methods, such as a TTL-level
digital output port, or mechanical toggle switches. The
device bus provides a two-wire serial bus structure and
protocol for connecting a number of devices to a single host
control interface, suitable for use in larger system and
sub-system applications. The driver interface contains
non-volatile configuration memory that is used to hold a
wide variety of attenuator and driver-dependent parameters, including serial number, attenuator cell dB values,
relay configurations, and switching requirements, which are
all accessible via the digital interface. This frees the system
designer from such low-level details, allowing faster integration. In either operational mode, the microcontroller
enters an idle condition during periods of inactivity, turning
off all on-board clocks, reducing EMI concerns, and lowering power consumption. On-board regulation for the digital
circuitry allows the programmable attenuator to operate
from a single input supply voltage.
