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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

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.

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.

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.

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.
