MC13150 CIRCUIT DESCRIPTION

General

The MC13150 is a very low power single conversion

The buffered output of the mixer is internally loaded,

resulting in an output impedance of 1.5 kΩ.

narrowband FM receiver incorporating a split IF. This device

is designated for use as the backend in analog narrowband

FM systems such as cellular, 900 MHz cordless phones and

narrowband data links with data rates up to 9.6 k baud. It

contains a mixer, oscillator, extended range received signal

strength indicator (RSSI), RSSI buffer, IF amplifier, limiting IF,

a unique coilless quadrature detector and a device enable

function (see Package Pin Outs/Block Diagram).

Local Oscillator

The on–chip transistor operates with crystal and LC

resonant elements up to 220 MHz. Series resonant, overtone

crystals are used to achieve excellent local oscillator stability.

3rd overtone crystals are used through about 65 to 70 MHz.

Operation from 70 MHz up to 200 MHz is feasible using the

on–chip transistor with a 5th or 7th overtone crystal. To

enhance operation using an overtone crystal, the internal

transistor’s bias is increased by adding an external resistor

Low Current Operation

The MC13150 is designed for battery and portable

applications. Supply current is typically 1.7 mAdc at 3.0 Vdc.

oscillator on continuously or it may be taken to the enable pin

to shut it off when the receiver is disabled. –10 dBm of local

oscillator drive is needed to adequately drive the mixer

(Figure 6). The oscillator configurations specified above are

described in the application section.

Enable

The enable function is provided for battery powered

operation. The enabled pin is pulled down to enable the

regulators. Figure 3 shows the supply current versus enable

RSSI

The received signal strength indicator (RSSI) output is a

current proportional to the log of the received signal

amplitude. The RSSI current output is derived by summing

the currents from the IF and limiting amplifier stages. An

external resistor at Pin 25 (in 32 pin QFP package) sets the

voltage range or swing of the RSSI output voltage. Linearity

of the RSSI is optimized by using external ceramic bandpass

filters which have an insertion loss of 4.0 dB. The RSSI circuit

is designed to provide 100+ dB of dynamic range with

temperature compensation (see Figures 7 and 23 which

show the RSSI response of the applications circuit).

Mixer

The mixer is a double–balanced four quadrant multiplier

and is designed to work up to 500 MHz. It has a single ended

input. Figure 5 shows the mixer gain and saturated output

response as a function of input signal drive and for –10 dBm

LO drive level. This is measured in the application circuit

shown in Figure 15 in which a single LC matching network is

used. Since the single–ended input impedance of the mixer is

200 Ω, an alternate solution uses a 1:4 impedance

transformer to match the mixer to 50 Ω input impedance. The

linear voltage gain of the mixer alone is approximately 4.0 dB

(plus an additional 6.0 dB for the transformer). Figure 6

shows the mixer gain versus the LO input level for various

mixer input levels at 50 MHz RF input.

RSSI Buffer

The RSSI buffer has limitations in what loads it can drive.

It can pull loads well towards the positive and negative

supplies, but has problems pulling the load away from the

supplies. The load should be biased at half supply to

overcome this limitation.
