Housed in a compact 3x3 mm (LP3) SMT QFN package, the RFIC requires minimal external components & provides a low cost alternative to more complicated double upconversion architectures. The RF output port is single-ended and matched to 50 Ohms with no external components. The LO requires -6 to +6 dBm and can be driven in either differential or single-ended mode while the Baseband inputs will support modulation inputs from DC - 250 MHz typical. This device is optimized for a supply voltage of +3.3V @ 108 mA and will provide stable performance over a +3V to +3.6V range.

LOP, LON Differential LO input ports. This device may be driven in either differential or single ended mode. In single ended mode, one port should be driven by the LO source while the other port may be terminated with a 50 resistor to ground. An external shunt 68 resistor is used to improve VSWR, while an external 100 pF capacitor is required to prevent DC supply voltage from appearing on the customer's PC board. VB2 Bias Voltage for the LO stage. This voltage will affect the Sideband Suppression, the Output Noise Floor and the Power Consumption. The ideal voltage range for this port is between +2.7 Vdc and +3.0 Vdc. The nominal current for this port is 5.3 mA. 5 Qn, Qp B 6, 7 Differential Quadrature baseband input. These are high impedance ports. The nominal recommended bias voltage is between 1.0 - 1.15V. The nominal recommended baseband input voltage is 800 mV peak to peak differential. By adjusting the DC bias voltage on ports Qn & Qp, the Carrier Suppression of the device can be optimized for a specific frequency band and LO power level. The typical offset voltage for optimization is less than 5 mV. The amplitude and phase difference between the I and Q inputs can be adjusted in order to optimize the Sideband Suppression for a specific frequency band and LO power level.

HMC495LP3 / 495LP3E v02.0705 SiGe WIDEBAND DIRECT MODULATOR RFIC, 250 - 3800 MHz Pin Descriptions (continued) Description Interface Schematic 13 Vcc1 Supply voltage for the mixer and output stages. Set to 3.3V for nominal operation. The nominal current for this port is 37 mA. 14, 15 Ip, In Differential In-Phase baseband input. These are high impedance ports. The nominal recommended bias voltage is between 1.0 - 1.15V.The nominal recommened baseband input voltage is 800 mV peak to peak differential. By adjusting the DC bias voltage on ports In & Ip, the Carrier Suppression of the device can be optimized for a specific frequency band and LO power level. The typical offset voltage for optimization is less than 5 mV. The amplitude and phase difference between the I and Q inputs can be adjusted in order to optimize the Sideband Suppression for a specific frequency band and LO power level. 16 Vcc2 Supply voltage for the LO stage. Set to 3.3V for nominal operation. The nominal current for this port is 64 mA.

U1 HMC495LP3 / HMC495LP3E Modulator PCB [2] 107309 Eval Board The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.

HMC495LP3 / 495LP3E v02.0705 SiGe WIDEBAND DIRECT MODULATOR RFIC, 250 - 3800 MHz B Baseband input frequency range is dependent on value of C4, C5, C9 and C10. The value of 10 pF was chosen to give a typical response of DC - 250 MHz. Input frequency range can be extended up to 1 GHz with possible degradation of LO leakage and broadband noise floor response by decreasing the value of C4, C5, C9 & C10. 10 MODULATORS - SMT Note: SO LE TE Application & Evaluation PCB Schematic O Characterization Set-up For price, delivery, and to place orders, please contact Hittite Microwave Corporation: For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, P.O. 978-250-3373 Box 9106, Norwood, MA 02062-9106 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: Phone: 781-329-4700 * Order online at www.analog.com Order On-line at www.hittite.com Application Support: Phone: 1-800-ANALOG-D Information furnished by Analog Devices is believed to be accurate and reliable.
