description
The Texas Instruments (TI) TRF1015 is a single-chip RF downconverter suitable for 900-MHz receiver
applications. It combines a low-noise amplifier (LNA), a buffered voltage-controlled oscillator (VCO), and an RF
mixer into a 20-pin SSOP package requiring very few external components.
Minimal power consumption can be further reduced by placing the required modules into operate mode and the
remaining modules into standby mode.
Three modes of operation are provided for both the LNA and the mixer: standby, low current, and improved
compression. The improved compression mode is suitable for applications that require full duplex capability.
The improved compression mode is suitable for maintaining receiver sensitivity in the presence of large
interfering signals and provides a low bit-error rate (BER) in digital modulation systems. The three modes of
operation are selectable in accordance with the presence of a high or low signal on PD1 and PD2, as shown
in Table 1.

MODE PD1 PD2
Standby L L
Low current H H
Improved compression L H
The LNA has a gain of 13 dB and a noise figure of 2.2 dB. LNA input and output characteristic impedances are
50 Ω. The single balanced RF mixer has a gain of 9 dB with a single-sideband (SSB) noise figure of 10 dB. The
VCO has a typical tuning range of 25 MHz using an external varactor and resonator. The VCO gain and tuning
range can be adjusted to meet the phase-locked loop (PLL) design requirement, with an external shunt and
feedback capacitors in series with the resonator. A buf fered output of the VCO provides phase locking capability
and can be configured for single-ended or differential operation.
The TRF1015 is offered in the 20-pin SSOP (DB) package and is characterized for operation from – 40°C
to 85°C free-air temperature.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
