HMC304MS8 General Description

The HMC304MS8 is a passive IP3 mixer in an 8 lead plastic surface mount Mini Small Outline Package (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 makes the HMC304MS8 ideal for high dynamic range applications.

HMC305LP4 General Description

The HMC305LP4 & HMC305LP4E are broadband 5-bit positive control GaAs IC digital attenuators with CMOS compatible serial-to-parallel drivers packaged in leadless QFN 4 x 4 mm SMT packages. Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2 dB. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ± 0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3V to +5V applied through an external 5k Ohm resistor is required.
