Its over 3 db gain range is controlled by a single control pin and Ω match is maintained over all settings. RF IN / V G 3 V C The MAAM-111 operates from MHz to 2 GHz and features flat gain control from +1 db to -2 db. At maximum gain setting (V C =Open) it delivers up to +18 dbm power and under db noise figure. Both reduce proportionally as gain is reduced with V C. The input IP3 exceeds + dbm at max/min gain settings. The device is typically biased with a V D = + V, V G = -. V, and a control of V to -2 V. Typical current is 7 ma with V G at -. V The MAAM-111 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. This device is assembled in a leadless 1. X 1.2 mm package that can be handled and placed with standard pick and place assembly equipment.

Proper ESD control techniques should be used when handling these devices.. Exceeding any one or combination of these limits may cause permanent damage to this device.. MACOM does not recommend sustained operation near these survivability limits. 6. Operating at nominal conditions with T J C will ensure MTTF > 1 x 1 6 hours. 7.

MAAM-111 MHz - 2 GHz Rev. V2 Evaluation Board Application Schematic VG C3 VD C2 RFIN VC C R1 3 1 2,, 6 FB C1 RFOUT Recommended PCB Layout Application Information for DC & pins For proper MAAM-111 operation a DC voltage must be applied at the V G (-.V) and V D (+V) pins in that order. Adjusting V G from -.2 V to -.6 V will change the quiescent current which can effect power and linearity if set below or above 7 ma. The gain of the MAAM-111 is controlled with the V C pin. The gain reduction is almost linear with V C between V to -2 V. Below -2 V internal ESD protection diodes will draw increasing current. The nominal open circuit voltage at the V C pin is +1 V and produces maximum gain and power. Limiting applications and zero crossing adjustment can be done by adjusting the V G and V C pins together. Parts List Component Value Package C1, C.22 µf 21 C2, C3.22 µf 2 FB 8 7 Ω 2 R1 1 KΩ 2 8. MACOM recommends using Murata part BLMGG71. 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 V G as applied to the input pin. It is recommended that the total ground (common mode) inductance not exceed.3 nh (3 ph). This is equivalent to placing at least four 8-mil (2-µm) diameter vias under the device, assuming an 8-mil (2-µm) thick RF layer to ground 3
