Laser Heads
The laser head is the source of the laser beam used in all laser motion and position measurement systems. The primary difference between laser heads is in the velocity, reference frequency and optical output power. Other considerations are size, heat dissipation, and input power requirements. Which laser you choose depends primarily on the application in which it will be used. For example, semiconductor lithography systems typically have faster moving parts (stages), and therefore need higher velocities than machine tool applications.

Microwave Wideband Synthesizer w/ Integrated VCO
ADF5356
The ADF5356 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave VCO design permits frequency operation from 6.8 GHz to 13.6 GHz at one radio frequency (RF) output. A series of frequency dividers at another frequency output permits operation from 53.125 MHz to 6800 MHz. The ADF5356 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate RF output frequencies as low as 53.125 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable.

Quad RF Driver
The Quad RF Driver contains four independent RF channels, each with an RF synthesizer, variable attenuator, and 1W power amplifier. The RF signal can originate from either the internal synthesizer or an external source via SMA input. All channels have independent frequency, phase, and gain settings and can be operated in one of two modes. The “Wideband” mode operates from 35MHz to 2GHz with a 3.472KHz resolution; over this range the frequency roll-off is approximately 0.5dB/100MHz. “Int-N Phase Adjust” mode allows the user to set and maintain a fixed phase relationship between all four channels. This mode is designed to operate between 300 and 460MHz with a 2MHz resolution. Two additional inputs are provided for an external frequency reference and digital modulation.
