HMC623LP4 / 623LP4E
RFIC DOWNCONVERTER SMT, 1.8 - 2.7 GHz
v01.0708
General Description
Features
Functional Diagram
The HMC623LP4E is a highly integrated
downconverter IC that operates from 1.8 to 2.7 GHz.
The HMC623LP4E incorporates a high dynamic
range, single-balanced mixer core with integrated
RF, LO and IF ampliers, making it ideal for
compact transceiver applications in GSM, WCDMA,
TD-SCDMA, WiBro and WiMAX. This versatile
converter RFIC operates with a low LO input
power level of only 0 dBm, provides up to 33 dB
conversion gain, and exhibits +39 dBm Output IP3.
The integrated RF amplier provides for an overall
noise gure of only 4 dB.
Low Noise Figure: 4 dB
High Output IP3: +39 dBm
Low Input LO Drive: 0 dBm
High LO to RF Isolation: 45 dB
High Conversion Gain: 33 dB
24 Lead 4x4mm SMT Package: 16mm2
Electrical Specications, TA = +25 °C, IF = 200 MHz, LO = 0 dBm, Vbias [1] = +5V [2]

N/C No connection necessary. These pins
may be connected to RF/DC Ground
3 RFIN This pin is DC coupled
and matched to 50 Ohms.
4 RES
This pin is used to set the DC current of the RF
amplier by selection of the external bias resistor.
See application circuit and bias resistor value table.
5 GND Backside of package has exposed metal ground
paddle that must also be connected to ground.
9 LOIN This pin is AC coupled
and matched to 50 Ohms.
12 VddLO Power supply for LO amplier.
An external RF bypass capacitor is required.
14 MIXIF
For applications not requiring operation to DC this
port should be DC blocked externally using a series
capacitor. Choose value of capacitor to pass IF
frequency desired. For operation to DC, this pin must
not sink/source more than 40 mA of current or failure
may result.
15 IFIN This pin is DC coupled.
An off chip DC blocking capacitor is required.
17 IFOUT IF output and DC Bias (Vcc) for the output stage.

Evaluation PCB
The circuit board used in the nal 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.
