MMIC Power Amplifier Boosts 17 To 24 G Hz MODEL XP1019-BD is a three-stage, monolithic-microwave-integrated-circuit (MMIC) gallium-arsenide (GaAs) power amplifier capable of 0.5-W (+27-dBm) output power at 1-dB compression from 17 to 24 GHz. The amplifier, which is rated for maximum input level of +19 dBm, provides 18 dB gain with ± 1 dB gain flatness across the 7-GHz operating bandwidth. It achieves error vector magnitude (EVM) of 2. 5 percent for 1-W output power and consumes a maximum of 500 mA current from a +5-VDC supply. The input return loss is typically 9 dB and the output return loss is typically 10 dB. The amplifier offers 45-dB reverse isolation. Fabricated with 0.15-micron GaAs pseudomor-phic high-electron-mobility-transistor (pHEMT) process technology, the chip amplifier is suitable for millimeter-wave point-to-point radio communications and military communications and tactical applications. It features an on-chip temperature-compensated output detector that can be used to regulate the power level (built-in power control) by varying the drain current. The MMIC chip is 100-percent RF, DC, and output-power tested and is given visual inspection testing according to MIL-STD-883 method 2010. The chip features near-hermetic surface passivation for protection. Mimix Broadband, Inc., 10795 Rockley Rd., Houston, TX 77099; (281) 988-4600, FAX: (281) 988-4615, Internet: www.mimixbroadband.com.
MODEL VTO-7500-67M/T is a low-noise funda-mental-frequency voltage-tuned oscillator ideal for communications and radar systems. It operates from 5 to 10 GHz with + 10 dBm typical output power and tuning voltages from 0 V ( 5 GHz) to 20 V ( 10 GHz). The tuning sensitivity ranges from 300 to 700 MHz/V. The oscillator, which provides a modulation bandwidth of 20 MHz, features sec-ond- and third-harmonic levels of typically –20 dBc and maximum spurious levels of –60 dBc.
The phase noise is typically –95 dBc/Hz offset 100 kHz from the carrier and a maximum of –135 dBc/Hz offset 10 MHz from the carrier. The pulling figure for a 12-dB return loss is typically 10 MHz and the pushing figure for total supply variation of 0.5 V is typically 40 MHz. The oscillator typically draws 65 mA current from a +5-VDC supply. It is available in a TO- 8 package or in a metal enclosure with SMA connectors.

MMIC Power Amplifier Spans 2 To 20 GHz MODEL MMA-022030B is an extremely broadband GaAs MMIC chip power amplifier capable of delivering nearly 1 W output power (+29 dBm) from 2 to 20 GHz. I actually boasts a usable frequency range of 1 to 22 GHz. With on-chip input and and output blocking capacitors, the amplifier requires only DC power-supply circuitry for operation. It features 5-dB small-signal gain across the full bandwidth with ± 1. 3 dB typical gain flatness. The input return loss is typically 9 dB and the output return loss is typically 8 dB. The MMIC amplifier delivers typically +28 dBm output power at 1-dB compression from 2 to 6 GHz, +28 dBm output power at 1-dB compression from 8 to 16 GHz, and +30 dBm output power at 1-dB compression from 18 to 20 GHz. The power amplifier exhibits a noise figure of 6. 5 dB and is rated for mean time to failure of 1 million hours at +85°C. It typically draws 490 mA current from a + 6.5-VDC positive supply while also requiring a second low-voltage (0- to –2-VDC) supply.
