A line of low-frequency digitizers includes units with as many as 24 synchronized input channels (with SMA connectors) for testing with 16-b resolution at sample rates to 250 MSamples/s or 14-b resolution at sample rates to 500 MSamples/s. The DN6.44x digitizers are ideal for testing arrays of antennas and sensors at analog bandwidths to 250 MHz. Switchable input impedances (50 Ω and 1 MΩ) and switchable input amplifiers provide six input ranges from ±200 mV to ±10 V. The digitizers are provided with operating software that controls the instrument from a host computer.

Spiral inductor coils are now available with inductance values from 1.5 to 300.0 nH featuring 1.5 to 18.5 turns. The spiral inductor coils are produced in seven different square dimensions, all 0.12 in. thick: 0.030 × 0.030 in., 0.040 × 0.040 in., 0.045 × 0.045 in., 0.055 × 0.055 in., 0.065 × 0.065 in., 0.075 × 0.075 in., and 0.085 × 0.085 in.
The spiral inductor coils, which are suitable for assembling microwave circuits and power supplies, are manufactured without chemical etching, using a thin-film process on quartz substrates with precision photolithography for excellent repeatability and consistency. A polymide coating is applied on the quartz substrate to eliminate the need for conformal coating. The inductors can be attached by means of nonconductive epoxy and electrically connected via wirebonds.

A pair of waveguide junction circulators provide frequency coverage at E-band, with model SNW-7137630818-12-C1 covering 71 to 76 GHz and mode SNW-8138630818-12-C1 operating from 81 to 86 GHz, both with better than 18-dB isolation and less than 0.8 dB insertion loss. A pair of waveguide junction isolators is also available for E-band use, with model SNW-7137630818-12-I1 spanning 71 to 76 GHz and model SNW-8138630818-12-I1 working from 81 to 86 GHz, each with at least 18-dB isolation and 0.8-dB maximum insertion loss across their full 5-GHz bandwidths. The waveguide components, which are particularly useful for “last-mile” E-band communications links, are each equipped with input and output ports with WR-12 waveguide and UG-387/U flanges.

The 01005BB104 broadband 100-nF multilayer ceramic capacitors provide resonant-free coupling and blocking across a frequency range from 16 kHz to beyond 65 GHz. Supplied in a case measuring just 16 × 8 × 8 mils, they achieve less than 1-dB insertion loss and better than 15-dB return loss on suitable circuit substrate materials. Rated for dv working voltages to 4 V dc, the capacitors are available with nickel-tin termination. Global models for the capacitors are available from Modelithics (www.modelithics.com) for performing computer circuit simulations with appropriate software.

Model FSW2476-50 is an intelligent interactive synthesizer (I2S) with an on-board microcontroller to simplify communications and programming. The low-noise signal source tunes from 240 to 760 MHz in 500-kHz steps with at least 0-dBm signal output power. It is designed for use with an external 10-MHz reference source, although the reference frequency is programmable. The synthesizer maintains excellent spectral purity for operating temperatures from −40 to +85°C, with typical phase noise of −95 dBc/Hz offset 1 kHz from the carrier, −98 dBc/Hz offset 10 kHz from the carrier, and −118 dBc/Hz offset 100 kHz from the carrier. Harmonics are typically −12 dBc while typical spurious suppression is −85 dBc. The synthesizer operates with +5 and +25 V dc bias and has typical settling time of 3 ms. It is supplied in a RoHS-compliant, surface-mount package measuring 0.94 × 0.94 × 0.23 in.
