HMC304MS8 / 304MS8E v01.0705 GaAs MMIC HIGH IP3 SINGLEBALANCED SMT MIXER, 1.7 - 3 GHz Typical Applications Features The HMC304MS8 / HMC304MS8E is ideal for: High Dynamic Range: +30 dBm IIP3 * PCS & 3G No External Components or Bias Required * 2.4 GHz ISM LO/RF Isolation: 30 dB * MMDS Ultra Small MSOP8 Package: 14.8 mm2 Functional Diagram General Description MIXERS - SGL-BAL - SMT 9 The HMC304MS8 & HMC304MS8E are passive high IP3 mixers in 8 lead plastic surface mount Mini Small Outline Packages (MSOP). This miniature single balanced MMIC mixer is constructed of GaAs Schottky diodes and novel planar transformer baluns on the chip while not requiring any external components. The RF port is balanced via the MMIC balun while the LO port is connected directly to the diodes. LO isolations are typically 20 to 30 dB. Excellent input IP3 performance of +27 to +32 dBm make the HMC304MS8(E) ideal for high dynamic range applications. Electrical Specifi cations*, TA = +25 C LO = +17 dBm IF = 100 MHz Parameter Min.
