CIRCUIT DESCRIPTION

General

The MC13144 is a low noise amplifier with programmable bias. This device is designated for use in the front end section in analog and digital FM systems such as Wireless Local Area Network (LAN), Digital European Cordless Telephone (DECT), PHS, PCS, GPS, Cellular, UHF and 800 MHz Special Mobile Radio (SMR), UHF Family Radio Services and 902 to 928 MHz cordless telephones.

Current Regulation/Enable

Temperature compensating voltage independent current regulation is digitally controlled by a 2 bit programmable bias/enable circuit.

Figure 1. MC13144 Internal Circuit*

LNA

The LNA is a unique and patented cascode amplifier with digitally (2 bit) programmable bias (see Internal Circuit Schematic). Typical gain of the LNA is 17 dB for minimum noise figure of 1.4 dB at 900 MHz.

Programmable Bias/Enable Circuit

This unique circuit allows for 3 bias levels and a standby mode in which the LNA can be externally biased as desired.

APPLICATIONS INFORMATION

Evaluation PC Board

The evaluation PCB is very versatile and is intended to be used across the entire useful frequency range of this device. The PC board layout accommodates all SMT components on the circuit side (see Circuit Side Component Placement View).

Component Selection

The evaluation PC board is laid out for the 4DFA (2 pole SMD Type) and 4DFB (3 pole SMD Type) filters which are available for applications in Cellular and GSM, GPS (1.2 to

1.5 GHz), DECT, PHS and PCS (1.8 to 2.0 GHz) and ISM Bands (902 to 928 MHz and 2.4 to 2.5 GHz). In the

926.5 MHz Application Circuit, a ceramic deielectric filter is used (Toko part # 4DFA–926A10).

LNA Input/Output

The LNA input impedance is the base of a common emitter cascode amplifier. The LNA output is the collector of the cascode stage and it is loaded with a series resistor of 400 Ω and a capacitor of 10 pF to provide stability .

Digitally Programmable Bias/Enable

The LNA is enabled by a 2 bit (En1 and En2) programmable bias circuit. The internal circuit shows the comparator circuit which programs the internal regulator. The logic table below shows the bias and typical performance.

Input/Output Matching

A typical application at 900 MHz yields 17 dB gain and

1.4 dB noise figure. In this circuit a series inductor of 5.6 nH is used to match the input and a shunt inductor of 8.2 nH which also serves as an RFC and a series capacitor of 0.9 p is used to match the LNA output to 50 Ω load impedance.

It may be desirable to use a RF ceramic or SAW filter after the LNA when driving a mixer to provide image frequency rejection. The image filter is selected based on cost, size and performance tradeoffs. Typical RF filters have 3.0 to 5.0 dB insertion loss. Interface matching between the RF input, RF filter and the mixer is shown in Application Circuit and the Component Placement View.

A typical application at 1900 MHz yields 13 dB gain and

2.7 dB noise figure. In this circuit a series inductor of 5.6 nH and a series capacitor of 1.0 pF are used to match the input and a shut inductor of 2.0 nH and a series capacitor of 2.0 pF are used to match the LNA output to 50 Ω load impedance.
