HMC374 / 374E v00.0405 LOW NOISE AMPLIFIERS - SMT 8 SMT PHEMT LOW NOISE AMPLIFIER, 0.3 - 3.0 GHz Typical Applications Features The HMC374 / HMC374E is ideal for: Single Supply: Vdd = +2.75 to +5.5V • Cellular/PCS/3G Low Noise Figure: 1.5 dB • WCS, MMDS & ISM High Output IP3: +37 dBm • Fixed Wireless & WLAN No External Matching Required • Private Land Mobile Radio Functional Diagram General Description The HMC374 & HMC374E are general purpose broad band Low Noise Amplifiers (LNA) for use in the 0.3 3 GHz frequency range. The LNA provides 15 dB of gain and a 1.5 dB noise figure from a single positive supply of +2.75 to +5.5V. The low noise figure coupled with a high P1dB (22 dBm) and high OIP3 (37 dBm) make this part ideal for cellular applications. The compact LNA design utilizes on-chip matching for repeatable gain and noise figure performance. To minimize board area the design is offered in a low cost SOT26 package that occupies only 0.118” x 0.118”. Electrical Specifi cations, TA = +25° C, Vdd= +5V Parameter Min.
