50MHz to 3GHz

RF Power Detector

with 60dB Dynamic Range

FEATURES

DESCRIPTION

The LT^®5534 is a 50MHz to 3GHz monolithic RF power

detector capable of measuring RF signals over a 60dB

dynamic range. The RF signal in a decibel scale is pre-

cisely converted into DC voltage on a linear scale. The

60dB input dynamic range is achieved using cascaded RF

detectors and RF limiters. Their outputs are summed to

generate an accurate log-linear DC voltage proportional

to the input RF signal in dB. The output is buffered with a

lowoutputimpedancedriver.TheLT5534deliverssuperior

temperature stability (typical output variation within ±±dB

over the full temperature range). The output responds in

less than 40ns to a large RF input signal.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 3: The linearity error is calculated by the difference between the

incremental slope of the output and the average output slope from

–48dBm to –±4dBm. The dynamic range is defined as the range over

which the linearity error is within ±3dB.

Note 2: Specifications over the –40°C to 85°C temperature range are assured

by design, characterization and correlation with statistical process control.

APPLICATIONS INFORMATION

Table 1. RF Input Impedance

The LT5534 is a logarithmic-based detector, capable of

measuring an RF signal over the frequency range from

50MHz to 3GHz. The 60dB linear dynamic range is

achieved with very stable output over the full temperature

range from –40°C to 85°C. The absolute variation over

temperature is typically within ±±dB over a 47dB dynamic

range at ±.9GHz.

The RF port is internally biased at V -0.±8V. The pin

should be DC blocked when connected to ground or other

matching components. A 47Ω resistor (R±) connected to

ground will provide better than ±0dB input return loss up

to 2.5GHz. An additional 2nH inductance in series with

R± will provide improved input matching up to 3GHz.

The impedance vs frequency of the RF input is detailed

in Table ±.

TheapproximatelinearRFinputpowerrangeoftheLT5534

is from –62dBm to –2dBm with a 50Ω source impedance.

However, this range can be adjusted either upward or

5534fc

LT5534

APPLICATIONS INFORMATION

downward to tailor for a particular application need. By

simply inserting an attenuator in front of the RF input, the

power range is shifted higher by the amount of the attenu-

ation. Moreover, due to the high RF input impedance of

the LT5534, the detecting range can be moved downward

for better detection sensitivity by using a narrow band

L-C matching network. By this means, the sensitivity of

the detector can be extended to as low as –75dBm. By

changing the value of resistor R±, the sensitivity of the

detector can be fine-tuned within the range from –75dBm

to –62dBm. Though the range is adjustable, the overall

linear dynamic range remains the same.

When the output is terminated with a load capacitance

C , the slew rate is then limited to 200µA/(C + ±.5pF).

For example, the slew rate is reduced to ±7.4V/µs when

C = ±0pF. A capacitive load may result in output voltage

overshoot, which can be minimized with a series compen-

sation resistor R2, as shown in Figure ±. The suggested

resistor values for various capacitive loads are listed in

Table 2.

Output Interface

The output interface of the LT5534 is shown in Figure 4.

The output currents from the RF detectors are summed

The optional RC network at the output (R2 and C5 on the

demo board) can also provide further output filtering, if

needed. The output bandwidth is primarily dictated by the

RCconstantofthislowpassfilterwhenitscornerfrequency

is less than 30MHz.

When a large signal (e.g., –2dBm) is present at the RF

input port, the output voltage swing can be as high as

2.4V. To assure proper operation of the chip, the minimum

resistive load at the output termination should be greater

than ±8kΩ.
