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. GND 20 Description 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.

Typ. Max. IF Input IF Frequency MHz IF Input Level dBm IF Impedance Balanced 130 -16 ohms 265 LO Input LO Frequency MHz 954 LO Input Level dBm -10 Operating Instructions The MD59-0039 is a highly integrated MMIC upconverter for the 800 – 900 MHz cellular band. The upconverter provides exceptional RF performance while drawing low DC current and is packaged in a low cost plastic package. It is an ideal candidate for light-weight, battery operated, portable handset applications. The MD59-0039 incorporates a differential IF amplifier, balanced mixer, LOA, RFA, variable voltage attenuator and a two-stage driver amplifier. Surface mount resistors, inductors and capacitors are used in conjunction with the MMIC to optimize the trade-offs between performance, tunability and ease of use. The schematic on the previous page shows the MMIC and required off-chip component values. The input impedance of the differential IF amplifier is matched externally to 50 Ω at the desired IF frequency with L1, C1 and C2. In addition, C1 and C2 also act as DC blocking capacitors for the differential IF inputs. A 06-03 case style can be used for L1 in most cases, but a 08-05 case style can be used if more gain is required. Capacitor C3 is a low frequency bypass capacitor. Inductors L2 and L3 help match the output of the differential IF amplifier to the differential input of the mixer, as well as providing RF chokes for the DC supply lines. 979 -5 0 image reject filter is required between the mixer output and RFA input to prevent upconversion noise at the image frequency from leaking onto the RF. This filter should have 50 Ω input and output impedance. The topology of both the input and output matching networks for the RF amplifier provides internal DC blocking capacitors, to prevent unwanted DC leakage. C6 and C12 are RF and low frequency bypass capacitors for the DC supply line. Capacitor C11 is a source bypass capacitor for the RF amplifier. Similar to the LOA, C11 and C12 should be placed as close the device as is practical. The VVA is a T-attenuator topology, providing better than 30 dB of attenuation from 800 to 900 MHz. The two-stage driver amplifier is nominally biased with 40 mA. An external resistor, R1, can be used to adjust the bias current of the second stage, thereby adjusting the linear output power. C4, C5, C9 and C10 are RF and low frequency bypass capacitors for the DC supply lines, for the first and second stage of the driver respectively. Capacitors C8 and C16 are the source bypass capacitors for the driver amplifier. The LO input port is matched on chip to 50 Ω. The LO buffer amplifier provides the voltage gain required to drive the gate of the mixer FET, while drawing a minimal amount of current. The LO buffer amplifies the –10 dBm input signal to the level required to drive the mixer. For optimum performance, it is recommended to use a drive level of –3 dBm. C7 and C14 are RF and low frequency bypass capacitors for the DC supply line. Capacitor C13 is a source bypass capacitor for the LO amplifier. The position of both C7 and C13 shown in the application circuit may affect the gain of the RF amplifier and should be placed as close the device as is practical. The mixer is a balanced floating FET mixer that provides exceptional linearity and isolation with low loss and no DC current. The mixer uses a high side LO frequency.
