* Solder Stencil Capability for PCB Production

A solder stencil capability has been added to the company's environmentally friendly systems for the production of prototype circuit boards. Stencils ensure the application of precisely defined amounts of solder paste to PC boards for optimum SMD connections, replacing compressed air techniques that often result in bubbles and bridges. A typical stencil can be produced in less than 10 minutes, which allows it to be used for short run prototyping work in design labs. Stencils accommodate pads as small as 10 mils in diameter with a minimum pitch of 20 mils between pad centers. Stencil thickness can be selected in the range from 3 to 5 mil. To complete the assembly, a ZelFlex stretching frame is included to mount the stencil for precise positioning. A low cost pick-and-place system is also available to automate component assembly.

SOFTWARE

* Harmonic Balance Simulator

MWJ5250 The HARBEC harmonic balance nonlinear simulator allows the designer to specify any number of fundamental tones for analysis and to co-simulate EM, linear and nonlinear circuits. The engine also uses artificial intelligence techniques to find and incorporate the best convergence strategy. In the GENESYS design environment, EM, linear and nonlinear circuit co-simulation is nearly transparent. Behind the scenes, GENESYS automatically recognizes the lumped components, removes them, adds internal ports and runs the EM simulation. The multiport data are transparently included in a circuit theory simulation. Once the initial design is complete, the lumped components can be interactively tuned or automatically optimized at high speed. This capability brings the accuracy of EM simulation to the design of nonlinear circuits. Price: $4990.

Available with an output frequency between 4.8 and 90 MHz and utilizing a full-size TO-8 quartz resonator, the oscillator performs to the stability required for Stratum II and IIe, GPS and TDMA PCS applications. The device operates over a ­30° to +70°C temperature range with steady-state power consumption of 5.5 W (typ). Typical RF output is +9 dBm ±2 dB sinewave (into a 50 W load) with < ?30 dBc harmonics and ?80 dBc spurious levels. The 270 series is also ideal for phase noise related issues, delivering ?100 dBc/Hz at a 1 Hz offset and ?155 dBc/Hz at a 10 kHz offset for a 5 MHz unit. Size: 1.423" × 1.071" × 0.765".

* Surface-mount DTCXO

MWJ5254 The QED 110-AH/BH digital compensation temperature-controlled crystal oscillator (DTCXO) achieves a stability of ±0.4 PPM over the operating temperature range of ?40° to +85°C. Designed for use in test equipment and man-pack and handset military radios, the unit operates with a supply voltage of 3.3 V DC (5 V upon request). It is available in a frequency range from 1.25 to 110 MHz, and current compensation is as low as 4 mA for the 3.3 V models, depending on frequency. The phase noise floor is ­150 dBc/Hz and the overall phase noise performance is matched to the frequency stability achieved. The
QED 110-AH/BH has a low aging rate, which in the first year is < ±1 PPM (typ) and ±4 PPM (typ) total aging in 10 years. Size: 0.79" × 0.51" × 0.39".
