Description

The MAMX-008611 is a floating FET mixer with an on-chip LO amplifier. The LO drive for the MAMX- 008611 can range from –5 to +5 dBm without severely impacting the mixer’s performance. The MAMX-008611 is ideally suited for cellular band communications handsets’ that can provide only minimal amounts of LO drive. Typical applications include frequency up/down conversion and IQ modulation and demodulation in digital receivers and transmitters. The MAMX-008611 utilizes a patented “floating-FET” architecture. The on-chip LO amplifier allows the MAMX-008611 to operate with as little as –5 dBm of LO drive making it an ideal choice for low power portable designs. The MAMX-008611 is fabricated using M/A-COM’s 0.5 micron low noise GaAs MESFET process. This process features full passivation for increased performance and reliability. The MAMX-008611 is 100% RF tested to ensure superior performance specification compliance.
