PROPOSED RFVC1833B RFVC1833B 8.35GHz to 9.50GHz MMIC VCO with Fo/2 and Fo/4 Outputs Features Multiple Frequency Outputs gn ■ ot F or N ew D es i RFMD's RFVC1833B 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 8.4GHz to 9.6GHz its monolithic structure provides excellent temperature, shock, and vibration performance. Output power (Fo) is +8dBm and is flat across the tuning voltage range of 1.5V to 14.5V. Phase noise is typically -114dBc/Hz at 100kHz offset. The device operates from a low supply current of 245mA which can be further reduced to 185mA by disabling the divider functions if not required. The RFVC1833B is available in a low cost 5mm x 5mm surface mount plastic overmolded QFN outline. Package: Plastic QFN, 32-pin, 5mm x 5mm x 0.85mm Fo: 8.35GHz to 9.50GHz Fo/2: 4.17GHz to 4.75GHz Fo/4: 2.08GHz to 2.37GHz ■ No External Resonator Required ■ Integrated Frequency Divider ■ Phase Noise: -114dBc/Hz at 100kHz Offset ■ Flat Output Power Over Frequency Tuning Range 1.5V to 14.5V ■ Low Power Consumption ■ Fo: 8dBm Fo/2: 6dBm Fo/4: -2dBm 5V/245mA (Divider On) 5V/185mA (Divider Off) 32-Lead 5mm x 5mm Plastic Overmolded QFN N Functional Block Diagram Ordering Information Applications ■ Point-to-Point Radio ■ Point-to-Multipoint Radio Bag with 25 pieces ■ Satellite Communications RFVC1833BSR Bag with 100 pieces ■ Test Equipment RFVC1833BTR7 7" Reel with 750 pieces ■ Military ■ Aerospace RFVC1833BS2 Sample bag with 2 pieces RFVC1833BSB Sample bag with 5 pieces RFVC1833BSQ RFVC1833BPCBA-410 Evaluation Board RF Micro Devices Inc. 7628 Thorndike Road, Greensboro, NC 27409-9421 For sales or technical support, contact RFMD at +1.336.678.5570 or [email protected]. ® ® DS140424 RF MICRO DEVICES and RFMD are trademarks of RFMD, LLC.
