16 Latest Projects RF Membrane Probe for testing to 50Ghz Multiple projects Typically taking weeks of development for probe. Worked with Cascade design team to defined a membrane probe for testing wafers components from 1Ghz to 40Ghz for AC, DC and RF parameters. RF parameters tested where S11, S12, S21 and S22. AC/DC parameters tested are for ADC and DAC, as well as, all digital scan and standard DC functions. Worked with customer to develop calibration standards for open/short and load on ceramic substrates for calibrating the different skews defined on the wafer. For S parameters on the device from 1Ghz to 40Ghz. Used external network analyzer E8363B with the ASL3K to test the devices on the wafer. RF Amplifiers and RF Switches Frequency 500MHz to 6Ghz Integra worked with an RF Silicon vendor to help specify the production level test requirements for their family of RF switches and RF Amplifiers to keep cost low and still provide complete coverage for the product. Designed the hardware and software taking into account all product skews fitting all designs into two separate boards for 12 different product skews with a design gear towards testing on the handler as x2 configuration for all devices. The hardware and software was designed with multi-site to reduce cost further down the road when volume increases. Test included S-parameters across the band, Gain, BW, P1dB, and Isolation. ASL3K used in testing of devices. 10Ghz Digital Device Testing Integra developed hardware and software used to test and qualify two 10Ghz components for space flight applications. All DC and AC parametric parameters defined in the manufactures data sheet were tested even though the manufacture in this case doesn t test AC parameters in production due to cost and time. AC testing involved, standard functional tests across all supply voltages and loads, propagation delays in sub pico-seconds and jitter under 1 nano-second. Special attention was given in the design of the hardware in order to accomplish jitter, rise and fall time and propagation delays on the devices. ASL3000 and High speed 20Ghz sample scope used for testing.
