HMC374SC70E
v01.0814
GaAs pHEMT LOW NOISE AMPLIFIER
0.3 - 3.0 GHz
General Description
Features
Functional Diagram
Single Supply: Vdd = +3.0 to +3.6V
Broadband Performance
Low Noise Figure: 1.6 dB
High Output IP3: +35 dBm
High Gain: 15 dB @ 0.6 GHz
Electrical Specications, Vdd= +3.3V
Typical Applications
The HMC374SC70E is ideal for:
• Cellular/PCS/3G
• WCS, MMDS & ISM
• Fixed Wireless & WLAN
• Private Land Mobile Radio
The HMC374SC70E is a general purpose broad-
band Low Noise Amplier (LNA) for use in the 0.3 -
3 GHz frequency range. The LNA provides 15 dB of
gain and a 1.6 dB noise gure from a single positive
supply of +3.0 to +3.6V. The low noise gure coupled
with a high P1dB (17 dBm) and high OIP3 (35 dBm)
make this part ideal for cellular applications. The
compact LNA is designed for repeatable gain and
noise gure performance. To minimize board area the
design is offered in a low cost SC70E package that
occupies only 0.089" x 0.053".

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads should be connected directly to the ground
plane similar to that shown above. 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.
