19-6309; Rev 0; 5/12 EVALUATION KIT AVAILABLE MAX2612 –MAX2616 40MHz to 4GHz Linear Broadband Amplifiers General Description The MAX2612–MAX2616 is a family of high-performance broadband gain blocks designed for use as a PA predriver, low-noise amplifier, or as a cascadable 50I amplifier with up to +19.5dBm output power. These devices are suited for many applications that include cellular infrastructure, private or commercial microwave radios, and CATV or cable modems. The operating frequency range extends from 40MHz to 4000MHz. The amplifier operates on a +3V to a +5.25V supply with input and output ports internally matched to 50I. The device family is available in a pin-to-pin compatible, compact 2mm x 3mm TDFN lead-free package.

Description PIN NAME 1, 3, 6, 8 GND Ground. Connect to PCB ground plane. FUNCTION 2 RFIN RF Input. Connect to an RF source through a 0.01FF DC-blocking capacitor. Internally matched to 50I. 4 EN/RBIAS Enable (MAX2612/MAX2613/MAX2614/MAX2616). Leave unconnected for normal operation or logiclow for disable mode operation. For applications that use the disable mode, it is recommended that the logic-high signal be derived from a high-impedance source such as an unterminated open-collector output or three-state (high-Z) output. Logic-low should be a low-impedance source or a switch to ground capable of sinking 10FA. RBIAS (MAX2615). Connect to a 21.5kI bias resistor to ground. The value can be adjusted to trade off supply current for OIP3. See the Applications Information section for further detail. 5 VCC DC Supply Input. Place 470pF and 10nf decoupling capacitors as close to pin as possible. Also place a 10FF bulk capacitor on VCC; this must be a tantalum capacitor with ESR > 2 and can be placed further away. 7 RFOUT — EP RF Output and DC Feed. Connect to DC supply through a 220nH inductor. Connect to output load through a 0.01FF DC-blocking capacitor. Exposed Pad. Connect to PCB ground plane by a 3 x 3 array of vias. Connect to ground lead (1, 3, 6, 8) land patterns and to layer 1 ground plane with thermal relief traces. ����������������������������������������������������������������� Maxim Integrated Products 8 MAX2612 –MAX2616 40MHz to 4GHz Linear Broadband Amplifiers Detailed Description Adjustable Bias Control for the MAX2615 While the MAX2612/MAX2613/MAX2614/MAX2616 are fixed biased for ease of use, the MAX2615 allows the current to be controlled by an external bias resistor connected from RBIAS (pin 4) to ground. In this configuration, the MAX2615 can be used over a range of current settings with an upper limit of ~150mA for an RBIAS of 10kI and a lower limit of 37.5mA for an RBIAS of 69kI. Values within this range allow optimized performance and power consumption for customer requirements. Applications Information Wideband Designs For LTE designs, the MAX261x family is ideally suited to minimize gain compensation over frequency while providing low noise and high OIP3 in a small (2mm x 3mm TDFN) but thermally efficient package. The same device can be used for multiple frequency bands without adjusting for gain slope degradation, a common artifact among pHEMT, InGaP, and GaAs gain blocks.

PACKAGE TYPE PACKAGE CODE OUTLINE NO. LAND PATTERN NO. 8 TDFN-EP T823+1 20-0174 90-0091 Input Overload Handling As a result of its simple Darlington architecture and rugged bipolar process, the MAX261x family provides an industry-leading +20dBm maximum input power rating. This inherently reduces the need for input protection circuitry while greatly minimizing the potential for damage to the device from intermittent RF surges. ����������������������������������������������������������������� Maxim Integrated Products 9 MAX2612 –MAX2616 40MHz to 4GHz Linear Broadband Amplifiers Revision History REVISION NUMBER REVISION DATE 0 5/12 DESCRIPTION Initial release PAGES CHANGED — Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.
