HMC323 General Description

The HMC323 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC amplifier that operates from a single Vcc supply. The surface mount SOT26 amplifier can be used as a broadband gain stage or used with external matching for optimized narrow band applications. The HMC323 offers 13 dB of gain and +19 dBm of saturated power while only requiring 57 mA from a 8.75V supply. Using a Darlington feedback pair results in reduced sensitivity to normal process variations and provides a good 50-ohm input/output port match. This amplifier is ideal for F systems where high linearity is required such as 2.2 - 2.7 GHz MMDS.

HMC323 Maximum Ratings

DC Voltage on Pin 1	8 Volts
Input Power (RFin)(Vcc = +5V)	+20 dBm
Channel Temperature (Tc)	175
Continuous Pdiss (Ta= 60) (derate 4.41 mW/ above 60)	507 mW
Storage Temperature	-65 to +150
Operating Temperature	-55 to +60

Note:
1. Select RBIAS to achieve desired Vcc voltage on Pin 1.
2. External blocking capacitors are required on Pins 1 and 3.

HMC324MS8G General Description

The HMC324MS8G is a high efficiency GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC amplifier that contains two un-connected amplifiers in parallel inside an 8 lead MSOPG package. When used in conjunction with an external balun, the outputs of the amplifier can be combined to reduce the 2nd harmonic distortion that is generated by the amplifier. With Vcc at +7.5V, the HMC324MS8G offers 13 dB of gain and with power combining and harmonic cancellation, +22 dBm of output power can be achieved. Using a Darlington feedback pair results in reduced sensitivity to normal process variations and provides a good 50-ohm input/ output port match. This amplifier is ideal for RF systems where high linearity is required. The design can operate in 50-ohm and 75-ohm systems which makes it ideal for CATV head-end and modem, and MCNS applications.

HMC326MS8G General Description

The HMC326MS8G is a high effi ciency GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC driver amplifi er which operates between 3.0 and 4.5 GHz. The amplifi er is packaged in a low cost, surface mount 8 leaded package with an exposed base for improved RF and thermal performance. The amplifi er provides 21 dB of gain and +26 dBm of saturated power from a +5.0V supply voltage. Power down capability is available to conserve current consumption when the amplifi er is not in use. Internal circuit matching was optimized to provide greater than 40% PAE.
