Its over 30 dB gain range is controlled by a single control pin and 50 Ω match is maintained over all settings. The MAAM-011100 operates from 400 MHz to 20 GHz and features flat gain control from +10 dB to -20 dB. At maximum gain setting (VC=Open) it delivers up to +18 dBm power and under 5 dB noise figure. Both reduce proportionally as gain is reduced with VC. The input IP3 exceeds +15 dBm at max/min gain settings. The device is typically biased with a VD = +5 V, VG = -0.5 V, and a control of 0 V to -2 V. Typical current is 70 mA with VG at -0.5 V Pin Configuration Pin No. Pin Name Function 1 RFOUT/VD RF Output 2 N/C No Connection 3 RFIN/VG RF Input The MAAM-011100 is ideally suited for use as a power amplifier driver, gain trimming block, or temperature compensation in the receive or transmit mode. Typical applications include Wi-Fi, LTE. Point-to-Point, IMS, EW, and A&D systems. 4 VC Voltage Control 5 N/C No Connection 6 N/C No Connection This device is assembled in a leadless 1.5 X 1.2 mm package that can be handled and placed with standard pick and place assembly equipment. 7 Paddle3 Ground 3.

Proper ESD control techniques should be used when handling these devices. 4. Exceeding any one or combination of these limits may cause permanent damage to this device. 5. MACOM does not recommend sustained operation near these survivability limits. 6. Operating at nominal conditions with TJ ≤ 150°C will ensure MTTF > 1 x 106 hours. 7. Junction Temperature (TJ) = TC + ӨJC * ((V * I) - (POUT - PIN)) Typical thermal resistance (ӨJC) = 67°C/W a) For TC = 25°C, TJ = 47°C @ 5 V, 70 mA, POUT = 15 dBm, PIN = 6 dBm b) For TC = 85°C, TJ = 107°C @ 5 V, 70 mA, POUT = 15 dBm, PIN = 6 dBm 2 M/A-COM Technology Solutions Inc.

V2 Application Schematic Evaluation Board VG RFIN VC C4 VD C3 C2 FB R1 3 4 C1 1 RFOUT 2, 5, 6 Application Information for DC & pins Recommended PCB Layout For proper MAAM-011100 operation a DC voltage must be applied at the VG (-0.5V) and VD (+5V) pins in that order. Adjusting VG from -0.2 V to -0.6 V will change the quiescent current which can effect power and linearity if set below or above 70 mA. The gain of the MAAM-011100 is controlled with the VC pin. The gain reduction is almost linear with VC between 0 V to -2 V. Below -2 V internal ESD protection diodes will draw increasing current. The nominal open circuit voltage at the VC pin is +1 V and produces maximum gain and power. Limiting applications and zero crossing adjustment can be done by adjusting the VG and VC pins together.

To bias properly, a DC voltage must be applied at the output pin. Typically this is done with a 2 element bias network that consists of a choke and a DC blocking capacitor. We recommend a ferrite bead for the main bias choke and quality capacitor for the DC block. A simple 1 KΩ resistor can be used as a RF choke for the negative VG as applied to the input pin. It is recommended that the total ground (common mode) inductance not exceed 0.03 nH (30 pH). This is equivalent to placing at least four 8-mil (200-µm) diameter vias under the device, assuming an 8-mil (200-µm) thick RF layer to ground 3 M/A-COM Technology Solutions Inc.
