RFMD launches narrowband MMIC VCOs

RF Micro Devices, Inc. has introduced the RFVC1831 – RFVC1844 family of MMIC voltage controlled oscillators (VCOs).

RFMD's RFVC1831 is a 5V InGaP MMIC VCO with an integrated frequency divider providing additional Fo/2 and Fo/4 outputs. With an Fo frequency range of 7.3GHz to 8.2GHz its monolithic structure provides excellent temperature, shock, and vibration performance. Output power (Fo) is +10dBm and is flat across the tuning voltage range of 2V to 12V. Phase noise is typically -114dBc/Hz at 100kHz offset.

The device operates from a low supply current of 230mA which can be further reduced to 165mA by disabling the divider functions if not required. The RFVC1831 is available in a low cost 5mmx5mm surface mount plastic overmolded QFN outline.

RFMD's RFVC1844 is a 5V InGaP MMIC VCO with an integrated frequency divider providing additional Fo/2 and Fo/4 outputs. With an Fo frequency range of 10.5GHz to 12.1GHz its monolithic structure provides excellent temperature, shock, and vibration performance. Output power (Fo) is +7dBm and is flat across the tuning voltage range of 2V to 12V. Phase noise is typically -113dBc/Hz at 100kHz offset.

The device operates from a low supply current of 280mA which can be further reduced to 220mA by disabling the divider functions if not required. The RFVC1844 is available in a low cost 5mmx5mm surface mount plastic overmolded QFN outline.
