CHV2241

CHV2241 K-band Oscillator with integrated Q-band Harmonic Mixer GaAs Monolithic Microwave IC Description The CHV2241 is a monolithic multifunction proposed for frequency generation and transposition. It integrates a K-band oscillator, a Q-band harmonic mixer and buffer amplifiers. For performance optimisation, an external port (ERC) allows a passive resonator coupling to the oscillator (at half output frequency). All the active devices are internally self biased. The circuit is manufactured with the P-HEMT process : 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form. +V F_lo = (F_rf - F_if)/2 ERC HIGH Q RESONATOR -V RF x2 LO_out_aux IF Multifunction block diagram 0 -1 Conversion loss (dB) -2 -3 -4 -5 -6 -7 -8 -9 -10 37 37,5 38 RF Frequency (GHz) 38,5 39 Main Features n K-band Oscillator + Q-band harmonic mixer n External resonator for centre frequency control and phase noise optimisation n High quality oscillator when coupled to a dielectric resonator n Low conversion loss n High temperature range n On chip self biasing n Automatic assembly oriented n Chip size 1.82 x 0.97 x 0.1 mm Typical conversion loss characteristic Main Characteristics Tamb = +25°C Symbol F_rf F_lo Pn Lc RF frequency Oscillator frequency Oscillator phase noise @ 100kHz (38GHz) Conversion loss Parameter Min 37.5 Typ 38.25 -100 7 Max 39 Unit GHz dBc/Hz dB (F_rf - F_if)/2 ESD Protections : Electrostatic discharge sens...
