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.
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
switched attenuator cells
(Figure 1). The attenuator
elements located in the
attenuator cell are created
by 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.

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.
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.
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.

【UFUN学习】开始之旅
期待很久的UFUN学习板今天板子终于到手了,迫不及待打开,板子真的小巧好看,特别精致。 不过还不知道怎么对这个板子作拓展,那个miniPCIE也不知道怎么用。 开始按照快读入门指南,搭建了开发环境。在KEIL中加载的程序,结果一不小心将JLINK升级了,后面就一直连接不上芯片了,悲催,明天再试试。只能使用ISP下载程序了。这里我使用的是mcuisp这个下载程序,感觉比文当中推荐的FlashLoader方便多了。这里是设置及下载效果。 这里的...
