Crystek's CVCO55FLM VCOs (Voltage
Controlled Oscillators) contain an extra modulation port
(TX modulation) for transmitter applications. The modulation port has a
negative slope and a typical modulation sensitivity of -20KHz/V.
from 172 to 210 MHz with a control voltage range of 0.2
to 4.8V. This VCO features a typical phase noise of -119 dBc/Hz @ 10KHz
offset and has excellent linearity. Output power is
typically 0 dBm.
Model CVCO55FLM-0172-0210 is packaged in the
industry-standard 0.5 x 0.5 in. SMD
package. Input voltage is 3V, with a max. current consumption of 9 mA. Pulling
and Pushing are minimized to 1.0 MHz and 0.5 MHz/V, respectively. Second
harmonic suppression is -20 dBc typical.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
