This is a 5.5-6.5 GHz GaAs MMIC Voltage Controlled Oscillator, which has On-Chip Resonator, +4.5 dBm Output Power, -97 dBc/Hz @ 100KHz Phase Noise, 20mA @ -5.0V Bias Supply and other features
The XQ1000‑BD VCO is a fully integrated GaAs HBT MMIC oscillator covering 5.5‑6.5 GHz. It features an on‑chip resonator, +4.5 dBm output power, and -97 dBc/Hz phase noise at 100 kHz offset. The device uses a cross‑coupled differential pair, on‑chip buffer amplifier and output balun, providing high reliability and low flicker noise.
Electrical specifications include a supply voltage of –5 V (Vee), a tuning voltage range of 0‑6 V (Vtune), and typical supply current of 20 mA. The part is supplied in a 0.160‑mm thick GaAs die with backside vias and gold metallization for either conductive epoxy or eutectic solder attachment. Handling instructions warn of GaAs hazards and detail recommended wire‑bonding and die‑attachment procedures.
