Description
M/A-COM’s MD59-0039 upconverter IC for cellular CDMA applications integrates a mixer, RF amplifier, IF amplifier, and LO buffer in a 5 millimeter (mm) square plastic micro leadframe package with exposd back side for improved high frequency grounding. M/A-COM designed the MD59-0039 to operate with balanced IF inputs and a single-ended RF output with a frequency in the 800 to 900 MHz frequency band. The maximum conversion gain is 24 dB, with a minimum 15 dB of gain range. The MD59-0039 can produce 5 dBm of linear output power, with an associated ACPR of - 56 dBc (IS-98). An internal LO buffer amplifier allows the device to accommodate low LO drive levels in the range of - 10 dBm to - 5 dBm. M/A-COM fabricates the MD59-0039 using a 0.5 micron low noise GaAs MESFET process. The process features full passivation for increased performance and reliability.
