Endwave extends multi-function upconverter MMIC range to 24GHz

Endwave Corp of San Jose, CA, USA, which designs and manufactures high-frequency RF monolithic microwave integrated circuits (MMICs) and modules, has added a pair of integrated frequency upconverters to its line of GaAs MMIC products.

Based on GaAs pseudomorphic high-electron-mobility transistor (pHEMT) technology, the highly integrated MMICs incorporate several frequency mixers, local oscillator (LO) amplifier or frequency doubler, and variable-gain RF amplifier circuitry, and suit a wide range of applications (including commercial and military transmitter systems).

The lower-frequency model EWU1509YF operates over an intermediate-frequency (IF) range of DC to 4GHz with LO signals of 6–19.4GHz at a nominal level of +2dBm to produce RF outputs of 10–15.4GHz. It achieves typical conversion gain of 16dB and +19dBm typical RF output power at 1dB compression. RF output levels can be adjusted via a 27dB RF gain-adjustment range. The output third-order intercept point is typically +28dBm at the maximum RF gain setting. The EWU1509YF is designed for low-power applications, drawing typically only 380mA current from a +4.5VDC supply.

The higher-frequency model EWU1809YF accepts IF signals of DC to 4.5GHz and LO signals of 8.5–12GHz and nominally +2dBm to produce RF output signals of 17–24GHz with typical conversion gain of 5dB. It generates +19dBm typical RF output power at 1dB compression, but allows this to be adjusted via an integrated 18dB RF gain-adjustment range. The output third-order intercept point is typically +25dBm at the maximum RF gain setting.

Both GaAs MMIC frequency upconverters feature integrated electrostatic-discharge (ESD) protection bias circuitry per Human Body Model (HBM) Class 1A requirements. The RoHS-compliant devices are housed in compact 5mm x 5mm, 32-lead, plastic-overmolded QFN surface-mount technology (SMT) packages and rated for operating temperatures from –55 to +85°C. All devices are 100% DC and RF tested and visually inspected to IPCA-610 requirements.
